摘要： A filled-gap magnetic recording head is provided comprising a flat or cylindrical contour head having a row of magnetic transducers in a gap region disposed between a rowbar substrate and a closure. The gap region is intentionally recessed to have a predetermined recess profile below a tape support surface. An electrical insulation layer is deposited on the tape support surface and on the recess profile of the gap region. The insulation layer prevents electrical shorting between the magnetic transducers and other conductive elements in the gap due to accumulations of conductive debris from the magnetic recording tape. A method of making the filled-gap magnetic recording head by intentionally recessing the gap region, cleaning the recessed profile and depositing an insulator layer is provided.

摘要： A method and system for secure data storage and retrieval is provided. A sequence of data units is divided into multiple subsets of data units corresponding to multiple data channels. The multiple data channels are assigned to multiple data writers based on a key code. Then, each subset of data units is transferred to a writer via an assigned channel for writing to storage media. Thereafter, to securely retrieve the stored data, each subset of data units is read from the storage media using a data reader. The original sequence of data units can only be reassembled using the key code for properly reassembling the subsets of data units into their original sequence.

摘要： In one embodiment, a method includes simultaneously writing tracks of data on a magnetic medium in a first direction using less than all available writers in an array of magnetic writers. The method also includes determining that an error has occurred when writing one of the tracks and terminating writing with the writer associated with the track on which the error occurred. In addition, the method includes simultaneously writing tracks of data on the magnetic medium in the first direction using a previously unused writer in the array of magnetic writers.
