How do I tell which side on a silver/silver disc is up?
There is one approach guaranteed to work: put the disc in the drive. If it works, you have it right. If it doesn't, eject it and turn it over.
Alternate approach: many discs have numbers or letters printed near the hub. If they appear to be written backwards, the disc is upside-down.
Another approach: hold the disc edge-on in front of you, so you're looking right across the surface of the disc. Tilt it up slightly, and look closely at the edge farthest from you. When it's the right way up you'll just see the label, when it's the wrong way up you'll be able to see some light through the polycarbonate.
Yet another approach: the area of the disc near the hub may feel different (one side may have a groove or a lump that the other doesn't). Figure out which side is which, then remember how the disc feels.
My name is Steve and I use +R. There I have said it.
I had no clue prior to this weeks class what the +/- meant. I had figured that R meant Read and RW meant Read/Write but since I don't use the technology very often I just didn't worry about it. It definitely makes you think about how cheap technology has become in certain aspects.
With CDs I was more in tune with the technology because I used if for music or backup. Nowadays with jump drives, iPods, storage on phone, etc - we carry data with us all the time - not just on a particular disk.
After class I came home and checked my DVDs just to see what Forum I belonged too. Thankfully it was the cool one.
get a double layer or super layer drive to solve this problem: it will be the easiest way to resolve this: it will become a standard in a few years anyway: then we will have to deal with triple layer?? flash drive might be the next player for cars: stick in the flash and play: same with video: flash drive for a tv: imagine that
I admit I ALWAYS was confused about those letters on CDs. Even when I was only using CDs for audio I could never remember if I needed a CD-R or CD-RW. Luckily, they started putting the word "music" on the label, making it much quicker for me to figure out. As far as DVDs, I have never attempted to burn one so I was unaware of the +/- difference. I think it is VERY cool that you can make your own DVD that looks like the ones that are professionally done. Hopefully, I will have the time to try and make one of these before the semester ends.
Things I learned about CDs and DVDs
I have always been aware of the -R and +R difference on CDs and DVDs, but have never truly looked into it, other than making sure that my machines were compatible. I have now heard in class and read further on the Internet and know that the differences are not substantial but cannot be ignored.
I was impressed by the amount of FREE software that is available, mostly for PCs only, for burning CDs and DVDs. I am also, looking forward to using software to format DVDs, I have never been through this process and it looks like this knowledge will be useful, in the future, on other projects.
I think that in this class I learned about burning Cd's in the past yah I could burn a data file to CD but other then that I have not done much past that point. I did not realize that their was so much to know about the different types of CD's and the options of using them. When I went to the store I just picked up whatever was the cheapest and available. I will definetly pay more attention now.
Something I learned is the difference between +R/+RW and -R/-RW. Each one of them is supported by different companies(DVD Forum or the DVD Alliance). The only company in common is Sony. According to DVD Alliance that supports +R/+RW DVDs the functional advantages of this format is that when burning a DVD, it is not required to format before ejecting it, it is allowed mixed recordings from PC & TV, and they are 100 % compatible with other DVD players. I usually purchase -R/-RW format and works fine for me but I might be start thinking on getting the + sign instead.
Like many of my classmates, I had barely paid attention to the dashes and plus signs on my cds. They are so cheap, one typically just grabs a thigh sized tube at Sam's club and uses it up slowly over a couple of years.
I also didn't realize that the dvd type cds were so picky.
"For example, DVD-R discs will work on Apple iMac computers, but DVD+R discs will not. The same is true for some recent DVD recorders, such as those made by Panasonic, Pioneer. . ."
Can't wait until the formats are more standard, flash drives work for me! I think they will get cheap enough to share out.
As I remember in the beginning of DVD format competition, I spent about $400 to buy a DVD+RW for backup video data. I didn't know it's not even compatible with +R(it can write +RW only) until reading the manual.
The unification of DVD format is a good news for users. Today, you can burn almost any kind of disks in a DVD writer. But I think the DVD industry is going to be an end in the future.
The need for DVD backup date/video is fading. Cost down of Flash and HDD makes it cheaper and easier to replace burning disk. It's faster not to mention.
The need of sharing photo and video has also been replaced by online album and Youtube. You can upload images and videos online and email the link to your friend instead of burn them a disk as it used to.
How long have you not used DVD burner? I think that's why DVD disks can be purchased at such low price now.
Unless I misunderstood, one thing I learned in the discussion about CDs and DVDs was that data CDs made with mp3s can now be played in car CD players. I remember when my daughters began burning their music years ago, often times the audio CDs wouldn't work in all car CD players.
I don't remember if this was discussed, but many DVDs too that I've burned have not been playable in all DVD players - maybe that has also been improved.
Assignment 12a
From this week’s material, I learned there are many CD types for recording all kinds of data such as audio, pictures and videos.
I also learned a Mixed-Mode/Hybrid CD contains data and music, Super Video CDs is similar to a DVD but has fewer features and a Mini-CD is used in Sony’s CD-R digital cameras only.
I already knew the differences between Audio CDs and Data CDs.
I had to learn the difference between the +/- cds and dvds a couple of years ago when my mother-in-law desparately wanted a dvd recorder that she would go on to never use. The first bunch of discs I bought did not work on any of the dvd players we had so I started researching it and found out why...not compatible. Fortunately the recorder does play dvds since that is all that she can figure out how to do.
I thought the discussion and explaination of the differences was right on and easily understood.
I have been burning CDs and DVDs for years now. I used to back up all my data from my hard drive onto CDs....then my photo collection grew too big for a CD to hold, and I switched to DVD data back up (now I use an external hard drive...ah technology. DVDs can record video and can store larger amounts of data. I burn a photo cd every week as I keep a photo journal of the growth and progress of my three-month-old triplet niece and nephews for my brother and sister-in-law. It's a convenient way of sharing my photos with them when I am not available to do a direct download to their computer.
After reviewing the material online about burning CDs and DVDs, I was surprised at how many different types of CDs there are, and the different functions. I knew there were differences in CD-Rs and CD-RWs, but did not realize there were also CDs specifically created for audio files or for storing pictures. I have always used the same CDs for everything. Like so many of the previous comments, I had never paid attention to the +/- on the disc labels, and would look for whatever was cheapest. The only time I would really pay attention to the DVD labeling is when I tried to buy discs for my video camera, and realized not all of the discs are created equal as you explained in class, and I could not figure out why they would not work with my camera until I went back and checked the manual and realized they were not compatible. I will have to definitely start paying more attention and looking a little bit close at the discs I buy in the future.
I have learned a great deal about DVDs. I have made my first DVD from my photostory, I have learned to use conversion software and websites, and I have learned to use two different audio editing programs.
The process, although difficult and frustrating at times, has helped me learn new skills that I look forward to utilizing more and more.
I enjoyed the DVD Maker in Windows. Very cool tool for personalizing a DVD.
I was also confused about which side do you record on when you are burning a cd. Which side is on the up? The CD/CD-RW/CD-R and all the other different alphabets was really throwing off until we discussed it in class. I still have issues from time to time with the meaning and purpose of the letters. I must admit that their was plenty that I did not know or understand about burning a CD. I now have a better working knowledge of how to burn CD's and which are the bets to use.
For me this was a little confusing, using a CD was a little more complex... I say that because I did not know what the letters meant on them and how they were to be used. Using CD's seems to be easier than using DVD's because CD's for me are used more often. However, the more I played with it, the more I realized that I can get used to this. I am not technology savvy and I think for me, it has really helped being able to learn new things.
I had no idea how many different types of CD there are. I also didn't realize there is free CD burning software out there. Pardon my ignorance, but does this work like a CD burner, or do you also have to have the hardware installed on the computer?
I also learned some fun information about the CD itself from the how stuff works web site...like that they are made out of plastic- just what we need, another petroleum product, and that the CD's data is arranged in a serious of tiny raised dots that can reach up to 3.5 miles if in a straight line!!
The home-made DVD programs are really spiffy- I definitely plan on learning how to do that for future projects.
Like everybody, I was unaware of the plus and minus signs behind the R. I don't use CDs much to backup work and I like to listen to the radio or original CDs. So, I don't deal with CDs very often. I liked learning about how to figure out the correct side of a CD to insert in the driver. Also I enyojed learning about the DVD menu creater. I'm planning to create other digital stories for my own purpose and would prefer to make a DVD menu. It makes it look much professional.
