20140363699 | CURRENT-PERPENDICULAR-TO-PLANE MAGNETORESISTIVE READ SENSOR - A current-perpendicular-to-plane magnetoresistive read sensor includes a stack of layers extending along a stacking direction, and an edge surface parallel to the stacking direction that forms at least part of a bearing surface of the read sensor, the bearing surface designed to face a recording medium. The stack of layers includes a first contact layer, a ferromagnetic free layer whose magnetic orientation varies according to an applied magnetic field, above the first contact layer, a non-magnetic layer above the ferromagnetic layer, a ferromagnetic spin injection layer above the non-magnetic layer, and a second contact layer above the spin injection layer, such that a current can flow between the second contact layer and the first contact layer along a current-perpendicular-to-plane direction, parallel to the stacking direction. The stack of layers further includes a series of structures extending along a direction parallel to the bearing surface and perpendicular to the stacking direction. | 12-11-2014 |
20150062740 | TAPE STORAGE SYSTEM - A tape storage medium includes a tape head for reading/writing data from/to a tape storage medium. At least one servo band along a longitudinal extension of the tape storage medium determines positional information. The servo band includes a set of servo tracks having a width extending along the longitudinal extension and arranged next to each other. A total of two different servo patterns are contained in the set of servo tracks. The tape head includes two servo readers. A width of each servo reader orthogonal to the longitudinal extension of the tape storage medium is at least half the width of a servo track. The two servo readers are offset from each other orthogonal to the longitudinal extension by d*wST+n*wST with wST being the width of the servo track, with 003-05-2015 | |
20150092291 | TAPE STORAGE MEDIUM - A tape storage medium comprises at least one data band and the data band comprises a set of data sub-bands adjacent to each other. Each data sub-band contains a set of data tracks along a longitudinal extension of the tape storage medium and adjacent to each other. Each data sub-band of the set comprises a pair of servo tracks for supporting to determine positional information. The set of data tracks of each data sub-band is arranged between the servo tracks of the pair. The servo tracks of the pair contain the same servo pattern. | 04-02-2015 |
20150092294 | READING FROM A TAPE STORAGE MEDIUM - In a method for operating a tape storage system, readback signals are simultaneously received from a set of data readers reading from data tracks of a set of adjacent data tracks extending along a longitudinal extension of a tape storage medium, wherein each data track of the set has a width and each data reader of the set has a width equal to or less than the width of a data track. Simultaneously to receiving the readback signals from the set of data readers readback signals are received from a servo reader arrangement containing at least one servo reader arranged laterally offset from one of the data readers by less than the width of a data track. At least one of lateral position, velocity, gain and timing information is determined dependent on the readback signals of each servo reader in the servo reader arrangement. | 04-02-2015 |
20150092295 | READING FROM A TAPE STORAGE MEDIUM - A method for operating a tape storage system includes simultaneously receiving readback signals from a set of data readers reading from data tracks of a set of adjacent data tracks extending along a longitudinal extension of a tape storage medium. Each data track has a width and each data reader has a width that exceeds the width of a data track. In the readback signal, of one of the data readers of the set a simultaneous presence of two defined waveforms is detected stemming from two different servo patterns arranged in servo sections of adjacent data tracks of the set. At least one of lateral position, velocity, gain and timing information is derived from a measure of the energy of the two defined waveforms detected in the readback signal of the data reader and applying this information in the operation of the tape storage system. | 04-02-2015 |
