摘要： A method and apparatus for reducing retry redundancy during disc read operations in a disc drive system are provided in which a number of physical sectors to be read from the disc during read operations is first determined. An attempt is then made to read all sectors of the number of sectors during a first disc revolution. Failed sectors of the number of sectors during the first disc revolution are also identified. A retry cycle is then performed on the failed sectors during a second disc revolution following the completion of the attempt to read all sectors of the number of sectors during the first revolution.

摘要： A method and apparatus for retrieving a single complete copy from multiple stored copies is provided. Information of each of the multiple stored copies is contained in a different set of sectors on disc surfaces in a disc storage system. Each different set of sectors can include at least one defective sector from which information is not recoverable. One copy from the multiple stored copies from which information is recoverable is selected. Defective sectors in the selected copy are identified. Replacement sectors are located from the multiple stored copies other than the selected copy. Information from the selected copy is merged with information from the replacement sectors to form the single complete copy.

摘要： A buffer random access memory has a first portion reserved for a defect table and a second portion reserved for data caching. A method of managing the buffer random access memory includes determining actual memory space of the first portion which is occupied by the defect table. This identifies unused memory space of the first portion of the buffer random access memory. The method then includes reallocating the unused memory space of the first portion of the buffer random access memory for use in data caching. Controllers and mass storage devices which implement the method are also provided.
