    摘要： Presented is a data channel with selectable components, such as encoders or decoders. Also, data having different data signal characteristics can be processed through a data channel based on the data signal characteristics. Further, a data channel may have independent encoding path and an independent decoding path. For example, a first data transmission having first data signal characteristics may be processed via a data channel based on a first selected set of components of the data channel and a second data transmission having second data signal characteristics different than the first data signal characteristics may be processed via the data channel using a second selected set of components in the data channel. The first selected set of components may be different than the second selected set of components, but may share one or more common components.

    摘要： Apparatus and method for improving operational performance of a disc drive by detecting defective servo burst patterns. A rotatable disc is provided with servo data which include a plurality of servo burst patterns to define a plurality of tracks. A head transduces the burst patterns to provide burst signals to a servo circuit which controllably positions the head with respect to the surface of the disc by determining a position error signal from a combination of the burst signals. The servo circuit identifies a selected servo burst pattern as defective in relation to differences between absolute values of successive pairs of peak amplitude samples from the burst signal.

    摘要： An apparatus and method for performing real-time, closed loop write verification in a disc drive having a rotatable magnetic disc and a head having read and write elements. During a write operation, the disc drive generates a write current signal indicative of input data to be written to the disc. The write current signal is applied to the write element, which generates a time-varying magnetic field to simultaneously induce a readback signal in the read element through magnetic coupling of the read element to the write element, and to magnetize the disc to write the input data to the disc. The readback signal induced in the read element is used to reconstruct a set of output data which is used to verify accuracy of the input data.

    摘要： Apparatus and method for simultaneously biasing multiple magneto-resistive read elements in a disc drive head/disc assembly. A preamplifier circuit sequentially applies read bias currents to successive pairs of heads of the head/disc assembly, wherein the read bias current applied to a selected one of each pair of the heads is used to transduce the servo data from the associated disc recording surface, and the read bias current applied to the remaining one of each pair of the heads is used to prepare the remaining one of each pair of the heads to subsequently transduce the servo data from the associated disc recording surface. The preamplifier circuit includes at least first and second read bias current sources and a head selection circuit.

    摘要： Window center settings in a read channel of a magnetic disk drive are controlled. The magnetic disk drive is suitable for reading data from a magnetic disk. A number of read operations are performed and data is read from the magnetic disk. Read errors are detected during the read operations. The number of read errors is recorded and error types are determined. Adjustment of the window center settings is controlled based on the number of read errors detected and the error types determined.

    摘要： A communications channel is provided that includes an encoder that receives user data and generates corresponding encoded symbols for transmission through a channel medium. A channel detector has an input coupled to receive an output signal from the channel medium and a reliability information output which produces reliability information regarding logic states of detected bits in the output signal. A binary reliability value is provide for each of the detected bits. The channel further includes a decoder having a reliability information input coupled to the reliability information output of the channel detector to generate corresponding user data words as a function of the binary reliability value.
