摘要： Systems and methods for maximizing shingled magnetic recording (SMR) drive capacity are described. In one embodiment, the SMR drive may include a main store to store user-accessible data, a media cache and media scratchpad to store internal data temporarily for internal operations, and a storage controller to process read and write requests. In some cases, the main store comprises a shingled media partition and an unshingled media partition. The storage controller may designate one or more data tracks from the shingled media partition as temporary data track guard bands. In some embodiments, a track range is selected based at least in part on at least one of an amount of data in the media cache, a size of the new data in the media cache, and an association between the new data in the media cache and data currently stored within the selected track range.

摘要： Method and apparatus for data storage using data compression techniques. In some embodiments, a data recording medium has a recording surface with a plurality of concentric tracks accessible using a moveable data read/write transducer. A cache memory temporarily stores data during transfer operations with the data recording medium. A controller is configured to, responsive to receipt of input write data, retrieve from the data recording medium to the cache memory a selected multi-block data set associated with the input write data, use the received input data to update the retrieved multi-block data set, compress the updated retrieved multi-block data set to generate a compressed data set, and write the compressed data set to a selected band of adjacent tracks on the data recording surface. A portion of the compressed data set is generated during movement of the data read/write transducer to the selected band of adjacent tracks.

摘要： An error corrector with a high use efficiency of a memory includes a memory, a bus device, an input buffer and an error correction module. The memory stores data. The bus device controls a memory access. The input buffer receives and temporarily stores a coded blockcode data, and writes the coded blockcode data in the memory through the bus device. The error correction module reads the coded blockcode data in the memory through the bus device and decodes it in rows and columns to thereby obtain decoded data and check bytes. The error correction module writes the decoded data in the memory through the bus device and discards the check bytes.
