My guess is that it doesn't have to be exactly
the right size.
I'm sure that when reading the data, it uses a servo-loop.
When writing, it would care but a little fast of slow shouldn't
make a big difference.
I'd assume it uses a PLL to recover the clock from the data stream.
If that's the case, the speed can drift quite a bit and it should still
get a good read.
