Hello.

What I know is that the same rotation speed of a disc allows ×2.4 for 12cm (×1.6 for 8cm diameter) faster data reading at the outer edge.

Because I am extremely knowledge thirsty and inquisitive, I thought that the community on VideoHelp can help me with my endless knowledge hunger. I keep a list of many questions I will maybe ask and topics (for example: calculating lossless digital zoom and loss value)

I would like to know the relationships of the following parameters of CD, DVD, HD-DVD and BD (and HVD?).

Rotation speed at CAV (unchanging rotation speed) ×1 or ×1.6 or ×2.4 = how many rotations per minute (RPM) or per second?

×1 CLV (same reading speed, varying rotation speed) speed = How many sectors per second?

Are the values slightly different for DVD+, DVD-, DVD-DL and DVD-RAM?

Is 1× on a CD 150 or 176.4 KiB/s? [2352×(1500/1764)=2000!].

This can also be useful for calculating the rotation speed acoustically.

SCSi is partially crippled. The PC only knows the disc rotation speed by the data rate, not by the disc drive rotation engine.

I hope that the community can provide useful information, and I would appreciate it.
