摘要： A data writer is described comprising: a memory to store at least one amount of source data that is to be written to a data storage medium; a processor to arrange the source data into subsets and generate ECC data in respect of each subset, wherein the source data and the associated ECC data are to be written to a data storage medium via a plurality of individual data channels, and wherein the ECC data comprises at least a first degree of ECC protection having a first level of redundancy in respect of a first subset and a second degree of ECC protection having a second level of redundancy in respect of a second subset; a plurality of data writing elements, each to write data from an associated data channel, concurrently with the writing by the other data writing elements of data from respective data channels, to a data storage medium; and a controller, to control the writing by the data writing elements of the source data and the associated ECC data to the data storage medium.

摘要： Certain embodiments of the present invention are directed to magnetic-tape drives that employ data-set-multiplexing magnetic-tape formats in order to achieve compatibility in magnetic-tape formats with respect to a variety of different magnetic-tape-drive tape-head configurations and dimensions. While previous and current magnetic-tape drives employ magnetic-tape formats that feature linear sequences of data sets along the tracks that are read or written during a single pass, or wrap, magnetic-tape drives of the present invention feature magnetic tape that contains data formatted according to a data-set-multiplexing magnetic-tape format, the data-set-multiplexing magnetic-tape format including, for each multiple-track wrap within a band, two or more parallel sequences of data sets written to the multiple tracks of the multiple-track wrap.

摘要： An example provides a system and method for decreasing a data transfer rate of a linear tape drive. The method includes detecting, within a linear tape drive, a first data transfer rate of a host computing system to determine whether the first data transfer rate is slower than a second data transfer rate of a magnetic tape head within the linear tape drive. The method also includes, in response to determining that the first data transfer rate is slower than the second data transfer rate, deactivating a specified number of data write elements within the magnetic tape head, wherein deactivating the specified number of the data write elements includes decreasing the second transfer rate.
