摘要： A dual actuator arm assembly system that uses two pairs of actuator-carriage arms (13-14) that linearly move over a stationary micro-rail (15-16) independently. The geometric shape of the two pairs of actuator carriage arms (13-14) conform to the arcs of the data tracks (22, 22a, 22b, 23, 23a) at an acute angle. System enables micro- actuation that is integrated to actuator arm (13-14) and is a function of its geometry. Uninterrupted data stream and sector coverage and thus parallel data transfer scheme is made possible. Each actuator (13-14) move only within a limited range (17, 17a, 18, 18a) of disk area, thus precision is increased, vibration is minimized and external transfer rate is speeded up and overall access time is shortened. Instant access to two quarters (20, 21) of the disk with two pairs of actuators (13-14) and to park these without landing the heads (26, 26a) -by positioning and constant fly height during idle mode, or when system is turned off, are introduced as what are new in the art.

摘要： The invention concerns a process for reading binary data recorded on a medium comprising at least one track, said binary data having been recorded on the medium at the frequency Fbit. The process is characterized in that it comprises a step during which the binary data are read at the sampling frequency Fe so as to establish a series of successive read samples ECH(k) for a given track, ECH(k) being the read sample with an order k, the phase rho (k) of each read sample with an order k being between 0 and 2 pi . An interpolation step enables an interpolated sample l(k), with a phase equal to pi corresponding to the read sample ECH(k), to be calculated from the read sample ECH(k) and the i+j read samples (ECH(k-i), ..., ECH(k+j)) which contain the read sample ECH(k) such that: I(k) = ak-i ECH(k-i) + ... + ak ECH(k) + ... +ak+jECH(k+j), the coefficients ak-i, ..., ak, ..., ak+j having values depending on the interpolation principle selected. The process also includes a validation step enabling information (VAL) to be generated for validating or invalidating the interpolated sample l(k). The invention applies in particular to the reading of binary data recorded on a large number of tracks.

摘要： A device for processing data recorded on a tape medium includes a first control part that controls a read head to read specific data recorded in a first area among data recorded in a first format on the tape medium. Data in the first format is recorded at a first recording density. The device further includes a second control part that controls a write head to write the specific data in a second area different from the first area of the tape medium and to write the specific data in a second format in a third area different from the second area of the tape medium. Data in the second format is recorded at a second recording density different from the first recording density. Moreover, the device may include a recording part for recording specific information that specifies a read position of other data among data recorded in the first format on the tape medium.

摘要： According to one aspect, methods and systems for determining the position of a recording head using existing data structures on magnetic storage media are provided. In one example, a recording head writes data to an active track on a magnetic storage tape, the recording head including a write element and a read element in a known spatial relationship, wherein the read element is configured to access at least a portion of a reference track when the write element is accessing the active track. A controller determines a relative position of the transducer element to the reference track and repositions the recording head to write data to the active track. The read element may be a backward channel reader or dedicated read element of the recording head for reading reference tracks during read and/or write operations.
