    摘要: In a method of carrying out defect management on reading data from a disk-shaped magnetic recording medium comprising a plurality of tracks separated into a user data area available to a user, an alternate area, and a management area, the method comprises the steps of retrying reading operation of data up to a maximum retry count when an error is detected on reading of data for a target sector in the user data area and of registering the target sector in a defect table in the management area and writing read-out data in an alternate sector in the alternate area in a case where a retry count is not less than a specific count when retry results in a success. Alternatively, the method comprises the steps of retrying reading operation of data up to a maximum retry count when an error is detected on reading of data for a target sector in the user data area, of overwriting read-out data in the target sector in a case where a retry count is not less than a specific count when retry results in a success, and of registering the target sector in a defect table in the management area and writing read-out data in an alternate sector in the alternate area in a case where an error is detected when overwritten data is reread from the target sector.

    摘要: In a large-capacity FD comprising a disk-shaped recording medium on which a plurality of tracks are arranged with concentric circles, each track is divided into a predetermined number of sectors having a length equal to one another. Each sector consists of a serve field and a data field. The servo field in each sector includes a sector number field in which a sector number and alternation contents of the magnetic disk medium are written and a track number field in which a track number is written. The sectors on each track may be assigned with serial sector numbers in a circumferential direction in order with skipping over any defective sector. The plurality of tracks may be separated in a radial direction into a plurality of zones each including at least one alternate track. The plurality of tracks may be separated in a radial direction into a user data area and an alternate area which has an information identification sector for storing historic information in respect to preparation of the disk-shaped recording medium.

    摘要: In a recording/reproducing device for use in recording and reproducing data on and from a recording medium while moving read/write head means relative to the recording medium in a moving direction, which comprises a carriage supporting the read/write head means and guided by a guiding member in the moving direction, and a voice coil motor comprising a voice coil and a magnetic circuit device for driving the carriage in the moving direction. The carriage has a coil holding portion by which the voice coil is fixedly held in the condition that the coil axis is arranged in the moving direction. The voice coil is applied with a driving electric current for driving the carriage. The magnetic circuit device is fixedly disposed adjacent to the voice coil to generate a magnetic field intersecting the driving current flowing through the voice coil, the voice coil moving in the moving direction together with the carriage by an interaction of the driving current and the magnetic field.

    摘要: In a disk protection method for protecting a magnetic recording disk upon ejection thereof from a removable magnetic recording/reproducing device by an eject mechanism through operation of an eject button, data writing relative to the magnetic recording disk is inhibited in response to a data write inhibit signal which is generated immediately after the operation of the eject button and before the eject mechanism actually starts the ejection of the magnetic recording disk. The eject mechanism actually ejects the magnetic recording disk from the removable magnetic recording/reproducing device in a condition where the data writing is inhibited.

    摘要: In a motor drive for driving a motor having three-phase coils in both a high rotation speed mode in which the motor rotates at a high rotation speed and a low rotation speed mode in which the motor rotates at a low rotation speed which is extremely lower than the high rotation speed, the motor drive includes a mode selection circuit for making a connection of the three-phase coils unipolar and bipolar connections on the high and the low rotation speed modes, respectively. A frequency generation pattern detects a rotation speed of the motor. On the basis of the rotation speed detected by the frequency generation pattern, a combination of a PLL circuit and a driving transistor drives the motor at the high and the low rotation speeds in the high and the low rotation speed modes, respectively.
