| 20080212224 | METHOD AND APPARATUS FOR CONTROLLING MOTION OF STORAGE MEDIA - A method of controlling relative motion of a data storage medium on which data is stored in data groups comprising tracks extending across the storage medium and a rotatable transducer for reading data from the storage medium includes determining from the data groups a start reread data group at which a data reread process is to start following detection of a read error condition in a preceding data read process. The method also includes obtaining a reread track reference value for use in controlling that relative motion during the data reread process using a track reference value difference stored in at least one track of at least one data group that is to be reread during the data reread process and a track reference value that was used in controlling that relative rotation during the preceding data read process. | 09-04-2008 |
| 20080316650 | Method for Changing the Configuration of a Media Drive Apparatus, Computer Readable Medium, and Media Drive Apparatus - Provided is method for changing the configuration of a media drive apparatus using a removable storage medium, the configuration of the media drive apparatus being stored as a plurality of configuration settings in a first non volatile memory of the media drive apparatus, the method comprising

| 20090046386 | DATA FORMATTING IN DATA STORAGE - A method of processing data comprising arranging data into a data group comprising a plurality of sub groups each said subgroup comprising a plurality of columns; for each column, determining at least one checksum data of said column; and for each column, storing the checksum data of that column within at least one said subgroup of the group, other than the subgroup to which said column belongs. | 02-19-2009 |
| 20090316553 | TAPE CONDITION IN A TAPE DATA TRANSFER APPARATUS - A tape data transfer apparatus operable to determine a tape damage condition of a tape received in the apparatus by determining a value representative of a tape pack size of the received tape and comparing the value representative of tape pack size with a tape pack size reference value that is read from the cartridge. | 12-24-2009 |
| 20100014182 | Controlling Motion of Storage Media - An apparatus for writing data to a data storage medium on which data is stored in data groups (N−3 to N+1) comprising tracks extending across and spaced from a reference edge of the storage medium includes a control system operable to cause i) a track reference difference value representative of a difference in a distance between the tracks of an existing data group (N−1) on the storage medium and the reference edge and a distance between the reference edge and the tracks of a data group (N) to be written to the storage medium such that it is the next data group following the existing data group (N−1) or ii) data from which such a difference value can be derived to be included in at least one of frame (A | 01-21-2010 |
| 20110022718 | Data Deduplication Apparatus and Method for Storing Data Received in a Data Stream From a Data Store - A method of storing data received in a data stream from a data source is disclosed in which prior to performing deduplication on the data stream a processor decompresses selected compressed data entities in the data stream to provide a decompressed form of the data entities in the data stream in place of the compressed form, the data stream including the decompressed data entities is deduplicated and the deduplicated data is stored to a deduplicated data store. | 01-27-2011 |
