    摘要: A system for generating an output signal indicating a specific area on an optical disc is disclosed. The system includes: a detecting circuit, a header signal generator, a protection circuit, a counter and an output signal generator. The detecting circuit detects pre-recorded address information on the optical disc to generate a detection signal. The header signal generator detects headers on the optical disc to generate a header signal. The protection circuit computes a first counter value and reloads the first counter value according to the detection signal and the header signal, wherein the protection circuit does not reload the first counter value twice successively due to the header signal. The counter computes a second counter value and reloads the second counter value according to the first counter value. The output signal generator generates the output signal according to the first counter value.

    摘要: An error correction code generator uses an additional static random access memory (SRAM) or a multi-symbol encoder to improve the encoding efficiency. During the encoding operation, the number of the data access of the dynamic random access memory (DRAM) with the row address switching can be reduced considerably via using the additional SRAM or multi-symbol encoder. Hence, the efficiency of the data access of the DRAM is improved and the encoding time of the error correction code generator is reduced.

    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.
