    摘要： A buffer management method is provided, particularly adaptable in an optical disc drive to access an optical disc. One or more data blocks are recorded to the optical disc in response to received write commands. Data blocks corresponding to the write commands are first buffered in a buffer of the optical disc drive. Thereafter, one or more write tasks may be organized based on the buffered write commands, each associated with a group of data blocks having consecutive destination addresses. A recording operation can be scheduled based on those write tasks, and the recording operation is performed to record the data blocks to the optical disc.

    摘要： A buffer management method is provided. A host issues a read command requesting access for a read data block and a write command requesting recording of a write data block. A write buffer is dedicated to store the write data block. A read buffer is dedicated to store the read data block. The method comprises entering the optical disc recorder into a write loop. During the write loop, the optical disc recorder triggering a write command handling procedure in response to the write command; triggering a read command handling procedure in response to the read command; and triggering a pre-recording procedure to prepare the write data block in the write buffer for recording. Wherein contents between the write buffer and read buffer are exchangeable during the write handling procedure, the read handling procedure or the pre-recording procedure.

    摘要： An optical disc drive is provided, mainly comprising a buffer, a processor and a driving module for accessing an optical disc. The optical disc drive receives a plurality of write commands. Each write command comprises a data block and a destination address. The buffer buffers data blocks to be recorded to the optical disc with corresponding write commands in either a random mode or a sequential mode. The processor schedules a recording operation based on the write commands, and selectively switches the buffer to the random mode or to the sequential mode based on arrangements of data blocks buffered in the buffer. The driving module is controlled by the processor to perform the recording operation, whereby the data blocks are recorded to the optical disc when a start recording condition is met. Specifically, the start recording condition varies with the random or sequential modes.

    摘要： A method of updating disc information of an optical disc includes checking whether a file system bitmap in a user data area of the optical disc had been updated, and updating disc information in a lead in area of the optical disc when the file system bitmap had been updated. By choosing an appropriate updating timing of the disc information, the present invention can reduce the risks of accidents such as power break down or abnormal host behavior occurring before the disc information is updated completely, and can prevent frequent access of locations storing the disc information.Besides one method to choose the appropriate updating timing of disc information is introduced in this invention, one method to recover the bitmap of disc information is also introduced if the optical disc has bitmap table and bitmap table is defective.

    摘要： A method for generating a recovered table of contents (TOC) for an optical disc having an damaged TOC and a predetermined file system includes selecting a recovering session on the optical disc; determining a recovering session starting location corresponding to a first SRR starting location in the recovering session; determining if the recovering session is a closed session; and if the recovering session is a closed session: determining a data size of the recovering session; calculating a next session starting location immediately following the recovering session by adding the data size of the recovering session, a temp-leadout size of the recovering session, and a temp-leadin size of the next session to the recovering session starting location; and constructing the recovered TOC by including information of recovering session and the next session starting location.
