Abstract

PURPOSE:To attain the shortening of the time necessary to record and reproduce information by executing the recording and reproducing action zigzag without returning to the starting part of a track for one track. CONSTITUTION:At one edge of a recording track on an optical card 1, an ID part 2 and a buffer part 4 are alternately provided at the interval of one track. An optical pick-up 21 scans the ID[n] of a second [n] track from the left, after the ID[n] is recognized, information is recorded to a user area [2n]. Continuously, when the information is recorded at a (2n+1)-th track, it falls in the lower direction as it is, and the information is recorded at a user area (2n+1) from the right at this time. After the ID[n+1] of a second [n+1] track is recognized, the information is recorded from the left to the user area [2(n+1)]. Continuously, the information falls in the lower direction as it does, and the information is recorded to a user area [2(n+1)+1] from the right at this time. Thus, by recording the information in the alternate direction, the wasteful time is eliminated and the time necessary to record is made shorter as a whole.
