    摘要： A tape transport control system suitable for use in tape recording apparatus which utilizes supply and take-up reels onto which the tape is wound. The control system is coupled to both the supply and take-up reels so as to generate detection signals which represents the rotation of the reels. The circuitry utilizes the detection signals to determine the point at which each of the reels in nearing its end, and sends a control signal to the tape transport circuitry to stop the rotation of the reels.

    摘要： In a seek operation, in which a head is moved to a target track, the detection output of a head-position detection unit is integrated in each track. Each integrated value is a positive or negative value proportional to an offset given to a center value obtained from the maximal value and the minimal value of the detection output. The center value is compensated for by a compensation value obtained by multiplying the integrated value by a coefficient. As a result, the offset is reduced and a highly precise positional detection is allowed.

    摘要： A recording/reproducing method and apparatus having the function of tracking a head on a data track formed on a recording medium of a lower-order specifications and on a data track formed on a recording medium of the upper-order specifications. During calibration, a controller 10 causes a locally maximum value and a locally minimum value of the signal level of a sine wave signal to be sequentially stored as the table information in a storage unit 11, as a magnetic head is moved by a head driving unit 7 in a direction perpendicular to the plural tracks. The sine wave signal is generated by an optical encoder and represents a substantially sinusoidal signal which completes its full cycle on the track basis. During tracking, the locally maximum value and the locally minimum value associated with a targeted track are read out from the storage unit 11 and a target sine wave level information is generated based on the generated locally maximum value and the locally minimum value. The magnetic head is tracked to the targeted track by a lower-order tracking controlling circuit 8a based on the generated target sine wave level information.

    摘要： A zone where a head is positioned is determined in a track to be one of zones 1 to 4 according to a combination of the polarities of phase-A and phase-B detection outputs having different phases, and the positional deviation of the head from the current position to the center of the target track is obtained from the phase-B detection output in the zone. The phase-B detection output is provided with a dead zone corresponding to a range where both detection outputs have a phase-difference error. Therefore, even if the phase difference has an error, the positional deviation of the head is accurately calculated.

    摘要： In a recording/reproducing apparatus, the controller has a function of increasing a count of incoming head move request pulses by one each time a head move request pulse is supplied while decreasing the count by one each time the magnetic head is moved over one data track by the magnetic head drive to provide a present count, and control the magnetic head drive to move the magnetic head at a speed based on the present count to a desired data track. Also, the magnetic head can also be moved over successive data tracks to a desired data track with a high accuracy.
