Cassette to CD Recorder
-
Optical drive's rotational mechanism Cassette to CD Recorder differs considerably from hard disk drive's, in that the last keep a constant angular velocity (CAV), in other words a constant numerator of revolutions per minute (RPM)
- With CAV, a tertiary school throughput is generally achievable at an outer disc area, as compared to inner area.
There are mechanical limits to how quickly a disc can be spun. Beyond a certain rate of rotation, around 10000 RPM, centrifugal stress can consideration the disc plastic to creep and possibly shatter. On the outer hook of the CD disc, 10000 RPM limitation roughly equals to 52x speed, but on the inner frontier only to 20x.
