Abstract

An optical recording method and apparatus for recording data to optical recordable medium are present. The optical recording apparatus at least comprises a PUH module and a verifier. The PUH module is used for recording a first number of data units to the optical recordable medium and reading a third number of data units, which are recorded to the optical recordable medium. The verifier is used for verifying the second number of data units being recorded. After the verifier verifies the second number of the data units, the PUH module follows to an initial position to record a third number of data units without any seeking operation. The PUH module keeps recording and reading and the verifier keep verifying until the plurality of data units being recorded and verified.

Description

【Technical field】 [0001] The present invention relates to a method and a device for recording data on a readable and writable optical medium, in particular to a method and a device for seamlessly transitioning from a verification operation to a recording operation so as to record data on an optical recording medium 【Background technique】 [0002] After an optical medium recording device records data on a readable and writable optical medium (such as an optical disc), it performs a verifying operation to confirm the reliability of the previously recorded data. When a defective block for recording data is found in the verification operation, the optical medium recording apparatus configures a replacement for the defective block, and this operation is called data defect processing. [0003] Please refer to FIG. 1 . FIG. 1 is a flow chart of a seeking operation, a recording operation, a verification operation and corresponding data units of a complete recording procedure in the ...
