Abstract
An apparatus for compensating a track when a track crossing signal is not generated due to an offset detection flag (ODF) region or a defect of a disk, comprises a missed track compensating processor for compensating a missed track signal generated when the light beam passes through the ODF region, and a track counter for mixing a pulse signal of a monostable multivibrator with a compensation signal output from the missed track compensation processor and counting the number of tracks. Thus, the missed track signal which is generated due to the ODF region and disk defects is compensated, thereby accurately counting the number of tracks over which the light beam cross.
