Abstract
Simultaneous recording on and playback from both sides of a double sided disk is achieved Sector addresses on both sides of the disk are read by respective scanners. One of address is renumbered according to a preset conversion rule which minimizes a time difference between instructions (for recording and playback on both disk sides) to be output to respective modems. Recording and playback operation are controlled according to the renumbered sector address.
