The types of optical disc

Anonymous

Hi

I heard and sometimes see in the Internet such types of optical disc::

CD±R/RW, DVD±R/WR, CD-ROM, DVD-ROM, DVD-RAM, CD±R DL, CD±RW DL, DVD DL, DVD±R DL, DVD±RW DL

First: The kind of discs I have been used to using, and seeing in the market are only:

CD-R, C-RW, DVD-R, DVD+R, DVD-RW, DVD+RW.

However, I've never ever used or even seen such these optical discs below at all

CD-ROM, DVD-RAM, DVD-ROM, CD±R DL, CD±RW DL, DVD±R DL, DVD±RW DL

Thus, I don't know if there are really existing in the market or not?

**Second:**I don't know if these abbreviations are short for normal names in the third column, or not. So, Could you please confirm for me if these abbrivations can decode to:

Abbrivation/shortten term	Disc/Media/Drive Category/ Disc type	Decoding
CD±R	CD Drive	CD± Recordable-Once Media, CD± Read-Only Access Media, CD ± write-once
CD±RW	CD Drive	CD± ReWritable Media
CD±ROM	CD Drive	CD± Recordable-Once Media, CD± Read-Only Access Media, CD± write-once disc
DVD±R	DVD Drive	DVD±Recordable-Once Media, DVD±Read-Only Access Media, DVD±write-once
DVD±RW	DVD Drive	DVD±ReWritable Media
DVD-RAM	DVD Drive	????????????
DVD±ROM	DVD Drive	DVD±Recordable-Once Media, DVD±Read-Only Access Media, DVD±write-once
CD±R DL	CD Drive	CD±Recordable-Once Media, CD±Read-Only Access Media, CD±write-once
CD±RW DL	CD Drive	???
DVD±R DL	DVD Drive	Dual-layer DVD-R and DVD+R discs to store significantly more data/Dual-Layer DVD -RW
DVD±RW DL	DVD	????

NOTE: I tried opening all discs on two computers with these speces :

I have a Windows 7 64Bit(SP1) with a HP laptop with i5Core. This is optical drive: Optical Drives hp CDDVDW TS-L633R Media Type DVD Writer Name hp CDDVDW TS-L633R Availability Running/Full Power Capabilities Random Access, Supports Writing, Supports Removable Media Read capabilities CD-R, CD-RW, CD-ROM, DVD-RAM, DVD-ROM, DVD-R, DVD-RW, DVD+R, DVD+RW, DVD-R DL, DVD-RW DL, DVD+R DL Write capabilities CD-R, CD-RW, DVD-RAM, DVD-R, DVD-RW, DVD+R, DVD+RW, DVD-R DL, DVD+R DL Config Manager Error Code Device is working properly Config Manager User Config FALSE Drive E: Media Loaded FALSE SCSI Bus 0 SCSI Logical Unit 0 SCSI Port 0 SCSI Target Id 1 Status OK ---------------------------------------------------------------------- Also, I have Windows XP SP1(32Bit) with another Pentium III processor(1GHz), and 256MB of RAM my Optical drive is: Optical Drives HL-DT-ST DVD-RAM GH22NP20 Media Type DVD Writer Name HL-DT-ST DVD-RAM GH22NP20 Availability Running/Full Power Capabilities Random Access, Supports Removable Media Read capabilities CD-R, CD-RW, CD-ROM, DVD-RAM, DVD-ROM, DVD-R, DVD-RW, DVD+R, DVD+RW, DVD-R DL, DVD+R DL Write capabilities CD-R, CD-RW, DVD-RAM, DVD-R, DVD-RW, DVD+R, DVD+RW, DVD-R DL, DVD+R DL Config Manager Error Code Device is working properly Config Manager User Config FALSE Drive F: Media Loaded FALSE SCSI Bus 0 SCSI Logical Unit 0 SCSI Port 1 SCSI Target Id 1 Status OK

Third:

IF you have a look at this screen shot below, you will see that CD Drive is listed as the type of disc on the propersties, although a DVD-R disc is inserted into optical drive. Thus, I think DVD Drive should be listed as the type of disc inserted.

Finally: What difference is there between 'CD-R/DVD-R' and 'CD-ROM/DVD-ROM'. Since I got confused when I noticed::

With some CDs-R is inserted into an optical drive, I see CD-ROM, insteaod of CD-R, since CD-R is inserted onto the drive.

With some CDs-R inserted into an optical drive, I see a CD-R

With some DVDs-R inserted into an optical drive, I see a DVD-ROM is listed as disc type, instead of DVD-R since DVD-R is inserted onto the drive.

With some DVD-R inserted into an optical drive, I see a DVD-R is listed as disc type.

mfg = manufacturer

You're expecting too much from people. If you can't research it, how do you expect them to? Too much information.
