Abstract
The invention is an offset setting system for an optical reading/writing apparatus having an optical pickup head reading/writing digital data under a predetermined velocity on an optical storage media. The apparatus sets the offset including a plurality of buffer blocks when the pickup head crosses storage tracks each time on the media and stop on a target storage track. The offset is to steady the pickup head to read/write data on a target block of the target storage track. A buffer time estimating module estimates an average time for the pickup head crossing a buffer block under a predetermined velocity, defining as a buffer time. The buffer blocks setting module records a steady time for the pickup head steadying to read/write data on the target block, and sets the number of the buffer blocks by a predetermined setting process in the offset based on the buffer time and the steady time.
