摘要： A magnetic write head having a tapered trailing edge and having a magnetic layer formed over a trailing edge of the write pole at a location recessed from the ABS, the magnetic layer being separated from the trailing edge of the write pole by a thin non-magnetic layer. The thin non-magnetic layer is preferably sufficiently thin that the magnetic layer can function as a portion of the write pole in a region removed from the ABS. A trailing magnetic shield is formed over the write pole and is separated from the write pole by a non-magnetic trailing gap layer. A non-magnetic spacer layer can be formed over the magnetic layer to provide additional separation between the magnetic layer and the trailing magnetic shield.

摘要： Techniques of the present invention include detecting a touchdown between a read/write head of a disk drive and a surface of a magnetic disk using multiple touchdown sensors located at an air-bearing surface (ABS). The multiple sensors increase the likelihood that a touchdown event—i.e., a portion of the ABS of the head contacting the underlying magnetic disk surface—will be detected. During touchdown, the portion of the head contacting the magnetic disk generates frictional heat which changes a characteristic (e.g., the electrical resistance) of at least one of the sensors located at the ABS. When the sensors are connected to a detection circuit, the changing characteristic may be monitored to identify a touchdown event. The touchdown sensors may be, for example, electrically connected in either series or parallel to the detection circuit. Thus, as long as the electrical resistance of one of the sensors is changed, a touchdown event may be detected.

摘要： A magnetic write head for use in a data recording system having first and second magnetic pole, the first pole having a P1 pedestal. An electrically conductive coil passes through a space between the first and second poles for inducing a magnetic flux through the yoke formed by the first and second poles. A bi-layer insulation layer disposed between the poles includes a layer of photoresist for preventing voids and a layer of alumina formed thereover to provide a structural brace to prevent recession of the P1 pedestal during manufacturing operations such as soda blast.

摘要： A method and apparatus for validating the electronic and coding of an incoming ideographic character, having a particular complexity and encoded according to a group of predetermined basic stroke elements and stroke sequencing rules to define an incoming character code, for use in association with a set of standard ideographic characters, encoded according to the group of pre-determined stroke elements and stroke sequencing rules to define standard character codes, each standard character having a certain complexity, the set being ordered according to the complexities of the standard characters. The method comprises the steps of specifying a portion of the standard set according to the complexity of the incoming ideographic character, searching such portion for at least a closest match between the incoming character and the standard character, and determining a sub-set of the portion, the sub-set containing at least one standard character code having the closest match with the incoming character code, and, selecting one member of the sub-set of closely match standard character codes as the correct code for the incoming character. The apparatus comprises a character complexity analyzer to determine the complexity of the incoming character. A comparison boundary setter specifies a portion of the standard set to be searched according to the complexity of the incoming character. A character comparator searches such portion for at least a closest match. A selector selects one of the most closely match standard character codes as the correct code for the incoming character.
