Abstract:
1. An offset setting system for an optical reading/writing apparatus having an optical pickup head, said optical pickup head reading/writing digital data under a predetermined velocity on an optical storage media, said optical reading/writing apparatus setting an offset including a plurality of buffer blocks when said optical pickup head crosses a plurality of storage tracks each time on said optical storage media and stop on a target storage track, said offset being used to steady said optical pickup head to read/write data on a target block of said target storage track, said system comprising: a buffer time estimating module for estimating an average time when said optical pickup head crosses a buffer block under said predetermined velocity, said average time being defined as a buffer time; and a buffer block setting system module for recording a steady time for said optical pickup head being steadied to read/write data, and setting the number of buffer blocks in said offset by a predetermined setting process based on said buffer time and said steady time.
