ABSTRACT:
A method of scanning multiple tracks uses an optical pickup to simultaneously emit a plurality of beams on a plurality of tracks on a disk, and satisfies the equations: N.sub.j =(N.sub.b -1)N.sub.g -1 and N.sub.r =N.sub.b N.sub.g -1. Here, N.sub.j represents the number of jumped tracks, N.sub.b represents the number of light beams, N.sub.g represents the interval between the light beams, and N.sub.r represents the number of reproduced tracks during a reproduction period.
