BUFFER MANAGEMENT METHOD AND OPTICAL DISC DRIVE

摘要

A buffer management method operates by receiving a read command, wherein the read command comprises a read destination address for designating an associated area of a storage media; receiving write commands, wherein each of the write command comprises a data block and a write destination address for designating an associated location of the storage media to store the data block; buffering the data blocks of the write commands in a buffer; generating a latest list, wherein the latest list comprises a plurality of buffer indexes indicating buffer areas for storing the data blocks associated with the latest certain amount of received write commands; and determining whether the read destination address of the read command is associate with the latest list.
