Why do hard disks/CD’s have to spin fast

Question

Can we write the data as a single track, that way they could spin very slowly, like a vinly record.

Thanks.

Answer 1

People have no patience.

When they click “next song” or “open file”, they want immediate response. If the disk spun at 60RPM it would take as much as a whole second before the device/computer responded. That’s unacceptable, so the disks need to spin faster, about 500 to 1000 times faster for computers and 10 times faster for a CD.
