Abstract
Herein disclosed is a method for storing data in a rotary type recording medium rotating in a predetermined direction in which the read of the information from one track to an adjacent track is conducted substantially continously when the head is moved in the first direction but discontinuously when the head is moved in a second direction reversed from the first one. The data is stored in at least one storage area on the recording medium such that data blocks are written in the order of tracks in the second direction, such that the newest data block leads in each track, and such that the data blocks in the storage area are read in the order from the newest one when the head is moved in the first direction.
