摘要： A processing scheme for digital storage media using multi-user detection to separate tracks of data or remove interference from neighboring tracks. In one embodiment, data is written on a plurality of tracks positioned sufficiently close together so that multiple tracks are detected simultaneously by the read access sensor. Upon scanning the surface for data, the read element simultaneously receives the data signals from a plurality of tracks. Joint detection signal processing resolves the interference and data bits from the multiple sensed tracks, enabling closer packing of data with minimal guard space.

摘要： A process for producing an iron cobalt alloy exhibiting magnetic anisotropy is disclosed. The alloy also exhibits a high magnetic moment, low coercivity and has uniaxial properties, making it suitable for use as the top pole of a magnetic recording head. The change in magnetic properties is brought about through the application of a high bias voltage during the deposition process.

摘要： A hard disk unit includes a disk, a controller microprocessor, a host bus interface, a buffer memory, a buffer memory controller, and a disk formatter. The bus interface receives write operations, and the buffer memory controller stores the corresponding write operation data in the buffer memory in the relative order in which the operations are received. The buffer memory controller subsequently transfers the data of a write operation from the buffer memory to the disk formatter, which formats the data and writes it to the disk. The buffer memory controller controls read and write access to the buffer memory. The buffer memory controller includes a set of address registers and a set of block count registers. The microprocessor loads the address registers with the addresses within the buffer memory of the data of two or more write operations. The microprocessor loads the block count registers with the size, in blocks, of the corresponding operations. The microprocessor then issues a single command to the buffer memory controller to transfer the data identified by the address registers and block count registers from the buffer memory to the disk formatter. The address registers and block count registers enable the buffer memory controller to transfer the data of several write operations in any order. Previous buffer controllers are typically capable of transferring the data of several write operations only in the same order in which the data is stored in the buffer memory.

摘要： The invention relates to a magnetic recording/reproducing device in which a reproduce head is positioned where the crosstalk between adjacent tracks in a magnetic disk is minimized to maintain an adequate transfer rate in a system involving great crosstalk. The removal of crosstalk ensures the reproduction of the recorded data and thus increases the reliability of the magnetic recording/reproducing device. The magnetic recording/reproducing device according to this invention includes a magnetic disk on which a plurality of tracks are concentrically formed, and data are recorded at different frequencies on adjacent tracks.

摘要： A magnetic recording medium includes an MgO layer (2), a first control layer (3), a second control layer (4), a magnetic layer (5), and a protective layer (6) on a substrate (1) in this order. An MgO layer is formed by sputtering, and it crystallizes in the hexagonal system and has a particular orientation. On the MgO layer are formed two or more control layers of metal using such a material that the difference in lattice constant between the control layers and a magnetic layer may not exceed 5%. The presence of these control layers allows the epitaxial growth of the magnetic layer to proceed preferably reflecting the structure of the MgO layer, and the magnetic layer can have an orientation (11.0) of Co desirable for high-density recording. The magnetic recording medium realizes high-density recording of more than 40 Gbits/inch .
