DVD+RW Question...

[rick090]

ok. when i got my Philips dvd+rw drive, i read that the dvd+rw format
is capable of LP, EP (or a.k.a CAV, CLV) recordings.
what is that means exacly?
can i burn movies like on VCR and double the disc size?
i need to cover that. THANKS!

Unless Philips didn't supply a help file, the two formats should be discussed. They are not analogous to LP or EP. CLV stands for Constant Linear Velocity, meaning the disk rotates slower as the pickup moves toward the outer edge. Bit density remains the same from inner groove to outer. CAV means Constant Angular Velocity, the disk rotates at a constant RPM. This means the inner groove is at the highest density, bit density decreases as the pickup moves outward. Only CLV is compatible with DVD players, and is the higher density.

I have no idea what that means. My Memorex dvds came with same advertisement. I have no idea how to record 8 hours with SEP, 6 hourse SLP, 4hours EP, 3 hours LP........
LOL

HQ, SP, LP, EP, SLP, and SEP seem to be carry-overs from the VHS days. I guess it's some marketing scheme they thought would help people, but really just confuses them. It loosely corresponds to the bitrate used when encoding...

IE:
HQ = 1 hr ~ 9000 kbps
SP = 2 HR ~ 4700 kbps
LP = 3 HR ~ 3000 kbps
EP = 4 HR ~ 2158 kbps
SLP= 6 HR ~ 1311 kbps
SEP= 8 HR ~ 887 kbps
