METHOD FOR CONTROLLING ECCENTRICITY OF OPTICAL DISK RECORDER LOADER

摘要

A method for controlling eccentricity of an optical disk recorder loader is provided to prevent degradation of reproducing and recording performances by counting the number of tracks a tracking traverse signal crosses during one rotation of the disk through a TZC(track zero count) signal and measuring the eccentricity using the track pitch of the disk. A method for controlling eccentricity of an optical disk recorder loader comprises the steps of: inserting an optical disk in the loader and focusing(202,204); detecting a traverse signal(206); counting the track crossing number of the traverse signal by a TZC(track zero count) signal(208); measuring a tracking count value of the traverse signal per one rotation of the optical disk, using an FG(frequency generator) signal(210); multiplying the track pitch by the measured tracking count value to measure the eccentricity(212); and carrying out the adaptive control of the loader according to the measured eccentricity(214).
