Abstract:
1. A method for reading a data segment recorded on a track on a data storage disc in a disc drive, the disc comprising a track circumferentially divided into a plurality of sequentially arranged data sectors accessible by a read/write head and storing the data segment, the method comprising steps of: (a) accessing, via the read/write head, the plurality of sequentially arranged data sectors and attempting to read data stored on each of the plurality of sequentially arranged data sectors as each sector is being accessed; (b) in response to encountering at least two errors while attempting to read at least two of the plurality of sequentially arranged data sectors, generating an instruction list identifying the at least two sectors on which the errors were encountered; and (c) executing a read error recovery procedure for reading data from the at least two sectors on which the errors were encountered, wherein the read error recovery procedure accesses and attempts to read data from the at least two sectors identified on the instruction list.
