    摘要: The present invention discloses an apparatus for converting a groove/land polarity on an optical medium, which comprises a physical identification (PID) detector detecting a first sector into a first PID value, a sector information unit providing an information including a second PID value indicative of either a second sector or at least one reference groove/land changing point, a sector counter counting a first value whose an initiation is set by the sector information unit based on the information and/or the PID detector based on the first PID value, and a comparing unit determining at least one oncoming groove/land changing points, based on when the first value approaches a second value either predetermined in or generated by the sector information unit according to said information.

    摘要: 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.
