Multiple track scanning method for optical pickup

摘要

A method for 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: Nj=(Nb-1)Ng-1and Nr=NbNg-1. Here, Nj represents the number of jumped tracks, Nb represents the number of light beams, Ng represents the interval between the light beams, and Nr represents the number of reproduced tracks during a reproduction period.
