ABSTRACT:
A procedure for reading data stored on a data storage disc in a disc drive is disclosed. The procedure involves reading data from one or more sectors on the data storage disc after an error occurred while initially reading the sector(s) pursuant to a read command issued by a host computer. During the initial read, the procedure logs information pertaining to the sector(s) on the disc where an error occurred. The logged information is then used during the procedure to retrieve data from the sector(s) in a single revolution of the disc. The procedure uses a skip mask, a vector buffer management list and a data throttling mechanism to administer a transfer of data from a disc to a host computer via a data buffer.
