How many pages of pure 16-bits Unicode text can a 650MB CD-ROM hold?
Each ASCII character requires one byte.
Assuming that a typical page of text holds about 2000 characters, then the CD-ROM can hold about :
650 MB/2 KB or 325,000 pages.
Unicode would store half as much, but with multilingual capability.
This result does not include space used for illustrations. It also does not include fonts and graphic formatting used for WYSIWYG display, which would require some space. The result gives a good idea of the incredible capacity of CD-ROMs.

DVD recorder won't copy onto DVD R disks but will copy to DVD-R disks. Why?
DVD-R disks are the most common in use today and that's why it'll record -R disks. The older recorders didn't have the software embedded in them to record on an R disk, but the newer generation machines usually will. Without going into a lot of techno-babble,the `R` was a positive recording system and the `-R` was a negative recording system. Most commercial movies you buy are -R disks as well, and since my computer will record both, I choose the -R disks because I'm relatively sure they'll play on any DVD player.
How does a DVD player remembers where a DVD stops?
Many of today's DVD players have a separate memory chip that keeps track of how far you've gone on a particular disc. When you stop a movie, then start it again, that memory chip tells the player where to start playing.
There are two basic types of production involved in CD-ROM's: All CD-ROMS are made with 4 basic layers, starting at the bottom: 1) A clear polycarbonate disc B) a reflective layer C) a protective layer D) top artwork layer Blank CD-ROMS: have no real data on them (the inner ring identifies the disk, maker, capacity, and production information) and normally the artwork layer is a writable surface to enable labeling the disk. Non-Blank CD-ROMS: have data already encoded and "pressed" into the disk - this allows for specific copy protections to be used, and normally has a unique artwork layer.

IS CD a random access storage device?
No.
Another Answer
Yes it is a Random Access storage device. You can tell this, because the last byte written on it's surface can be accessed without reading all the data bytes on the disk written before it. The drive can go directly to the last byte and read it off the surface. A tape (optical or magnetic) storage medium is Sequential, but an optical disk (CD/DVD) is Random.
