Abstract:
A read/write head (110, 214) includes a bottom shield (203) and a shared shields (204, 300, 302, 404, 406, 504, 506). The shared shield includes a first domain (320, 330, 416, 418) and a plurality of closure domains (321, 323, 325, 331, 333, 335). The read/write head also includes a magnetoresistive sensor (205) deposited adjacent an air bearing surface (222) between the bottom shield and the shared shield. The magnetoresistive sensor includes a magnetoresistor (308, 310, 420, 422, 520, 522) aligned with the first domain. Non-magnetic material (224) separates the magnetoresistive sensor from the bottom shield and the shared shield. The shared shield includes a shaped feature (400, 402, 500, 502, 600, 602, 604) that defines an unambiguous direction of magnetization for the first domain.
Abstract:
A shock protection assembly for a disc drive includes a protective cover (230) mounted as the lowest portion of the disc drive. The disc drive includes a base plate (102) and two mounting rails (202), wherein a printed circuit board assembly (200) is attached to the base plate between the two mounting rails. The protection cover is mounted to the base plate to cover a majority of the printed circuit board assembly while extending a predetermined distance below the mounting rails to shield the mounting rails and the base plate from contact. The shock protection assembly may further include a shock damper positioned between the protective cover and the printed circuit board assembly.
Abstract:
During self-servowriting, burst information is written within slots defined on tracks of a recording medium. In writing the burst information, write to read interference, caused by large offsets in separate read and write elements of a recording transducer, is to be avoided. In order to avoid the write to read interference, the slots are carefully chosen. The choice of a particular slot can be independent of any predefined order, such as a successive order. Further, the order in which slots are chosen may be altered during the propagation process.

Abstract:
An information handling system, such as a magnetic disc drive, includes a method and apparatus for performing an onboard microtrack profile test for characterizing the head sensitivity of a magneto-resistive head. The method comprises formation of a very narrow written signal on a track and execution of a microtrack scan (624) based on the count feature (622) from the variable gain amplifier (VGA) from the read channel (620).
Abstract:
A magnetoresistive (MR) sensor for use in a magnetic storage system including a magnetic storage media having multiple concentric microtracks with information stored thereon. The MR sensor includes a plurality of generally parallel layers that form an MR stack. The MR sensor also includes a top shield and a bottom shield that are spaced apart on opposite sides of the MR stack in a longitudinal direction. The MR sensor further includes a first and a second side shield spaced apart on opposite sides of the MR stack in a transverse direction. The top shield, bottom shield, first side shield and second side shield substantially surround the MR stack.
Abstract:
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.
Abstract:
Track positioning of a scanning tape head in a helical tape system may be adversely affected by relative offsets between elements in read element pairs and in write element pairs accessing synchronization patterns. Compensating for variations in the position of read and write elements accessing a given pair of data channels is accomplished by using the relative offset of the first detected synchronization patterns in each pair of data channels as a measure of the relative locations of write elements producing the synchronization patterns and read elements accessing the synchronization patterns. This relative offset is then used to correct subsequent synchronization patterns. This relative offset is then used to correct subsequent synchronization pattern readings taken from the data channel pair.

A magnetic thin film which can be produced by the same dry process as that for a magnetoresistance element forming a reproduction head, and is provided with excellent soft magnetic characteristics suitable as a recording head magnetic pole material and having a saturation magnetic flux density of at least 2T and a coercive force of up to 2 Oe; a production method therefor; and a magnetic head using it, a magnetic recording device and a magnetic device. The magnetic thin film is characterized by being an iron carbide film having a martensite ( alpha ') phase as its main phase and containing at least carbon and iron as constituting elements. This iron carbide film is preferably in a form consisting of alpha ' single phase, is a magnetic thin film specified by having a diffraction peak from alpha '-phase's (002) plane observed as a main peak by an X-ray diffraction method or an electron beam diffraction method, is provided with a body-centered tetragonal structure, and has a difficult-to-magnetize c-axis approximately vertical to the film surface and an easy-to-magnetize c-plane approximately horizontal to the film surface.
