摘要： A magnetic disk system comprises a magnetic head for writing data on and reading data from a magnetic disk as a recording medium and a magnetic disk unit having a head positioning mechanism for positioning the magnetic head on a selected track of the magnetic disk without forming servo information on the magnetic disk. The magnetic head comprises an MR film which is disposed parallel to the direction of the width of a track of the magnetic disk, current supplying electrodes disposed to be in contact with both ends of the magnetic film which are opposed in the direction of the track width and a signal detecting electrode disposed between the current supplying electrodes to be in contact with the MR film. The width of the signal detecting electrode is less than 1/3 of that of the current supplying electrodes. The magnetic disk system permits highly accurate alignment of the magnetic head with closely spaced tracks.

摘要： A magnetic disk storage device has a magnetic disk with a storing/reproduction region formed thereon and a head slider facing the disk surface with a plurality of parallel projections to generate an air bearing. Magnetic heads each having a head gap are provided in the projections and have an interval between head gaps of at least 1/N of the width of the whole storing/reproduction region of the disk where N is the number of heads. The device makes it feasible to increase the number of heads per disk and to shorten the seek distance without increasing the weight of the head actuator.

摘要： According to one embodiment, there is provided a disk drive that can perform dynamic offset control (DOC). The disk drive has a magnetic head, a disk, and offset calculating modules. The magnetic head has read head. Offset-measuring position data is written in a non-servo area provided in the disk. The read head reads the offset-measuring position data from the disk.

摘要： A partial response (PR) waveform generator generates a digital value sequence of an expected PR waveform based on the output of a soft-decision Viterbi detector included in, for example, a first-stage decoder unit incorporated in an iterative decoder. The generator also generates flag information indicative of whether reliability of the digital value sequence is low or high, in parallel with the generation of the digital value sequence. An error detector detects error values in a PR equalized sample value sequence, needed for feedback control of a control target, using the digital value sequence of the expected PR waveform as a digital value sequence of a reference waveform. An error output controller controls the output of the error values detected by the error detector in accordance with the state of the flag information generated by the generator.

摘要： A light pulse multiprocessing unit has a half mirror and N delay elements, each having a refractive index n. The N delay elements are arranged on one side of the half mirror from one end of the half mirror toward the other end and have thicknesses Δ, 2Δ, . . . , 2N−1 Δ different from each other, where Δ is the smallest thickness. The half mirror is placed in parallel in the proximity of an intermediate position between two mirrors and the N delay elements are arranged between one of the mirrors and the half mirror. Each of the N delay elements is a plane-parallel plate and is placed at an angle such that the direction of the normal line of the surface of the plane-parallel plate is different from a direction followed from one end of the half mirror toward the other end.
