ABSTRACT:
The present invention discloses an apparatus and method for accurately converting a groove/land polarity upon a groove/land track change on an optical medium, by way of initially deciding a reference groove/land changing point or a decoded PID of any one specific sector formed on the optical medium. By counting a specific number of sectors from the reference groove/land changing point or the specific sector, a subsequent groove/land changing point will easily be approached for converting the groove/land polarity, and even the other oncoming track changing points on the optical medium also can be determined.
