    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 method for defect management of a rewritable optical disc is provided. The rewritable optical disc has a data area comprises recording units for storing a target data and a replacement area comprising first replacement units for replacing defective recording units of the data area. First, a fragmented status of the target data is calculated, wherein the fragmented status reflects a dispersion level of the first replacement units in view of a distribution of the defective recording units. The fragmented status is then compared with a threshold value to determine whether to perform a defragment operation about the target data. Finally, the defragment operation about the target data is performed by rearranging the first replacement units in accordance with the sequence of the defective recording units.

    摘要: The invention provides a method for data recovery. In one embodiment, a memory comprises a plurality of pages for data storage. First, first data is obtained from a host. A first page for storing the first data is then selected from the pages of the memory. A start page link indicating the first page is then stored in the memory. The first data, a first page link indicating a next page, and first FTL fragment data corresponding to the first page are then written into the first page. Next data is then obtained from the host. The next data, a next page link indicating a subsequent page, and FTL fragment data corresponding to the next page are written into the next page.
