摘要： A drive method and system are disclosed for a stepping motor typically having several sets of four phase windings on respective stator poles of annular arrangement, and a rotor having several alternating N and S poles at constant circumferential spacings. Normally, the windings are sequentially excited as by a single or two phase drive mode to cause the rotor to rotate by increments. For stopping the rotor in a required angular position, any one or two of the four phase windings are excited in a normal direction to polarize the associated stator pole or poles into one polarity to attract one of the opposite poles of the rotor. Further, the other phase windings on both sides of the noted one or two windings are excited in the reverse direction, as by the discharge of capacitors, with the consequent polarization of the associated stator poles into the opposite polarity. The stator poles thus polarized into the different polarities make possible the positive detenting of the rotor in the required angular position.

摘要： In a stepping motor of the type having one or more sets of four phase windings on respective stator poles, with the four phase windings being excited sequentially to cause the rotation of a rotor having magnetic poles, a drive method and system are disclosed for stopping the rotor in exact angular positions required. Since the stator can less magnetically control the rotor when the latter is positioned with its magnetic poles in axact alignment with the stator poles, the stator windings are sequentially excited in such a manner that upon termination of the sequential excitation, the rotor comes to a stop in a position angularly displaced to a predetermined degree in a predetermined direction from a position of exact alignment with the stator poles. Basically, for stopping the rotor in such angular positions, at least two of the four phase windings are excited at a time with currents of predetermined different magnitudes.

摘要： A flexible magnetic disk drive has an index sensor which, during the rotation of the magnetic disk, generates a series of index pulses representative of the angular position of the magnetic disk. The index pulses are delivered to a host system only when a drive select signal supplied therefrom to the disk drive is in a prescribed state dictating the execution of reading or writing by that disk drive. Since the host system responds to the leading edges of the incoming index pulses for formatting the magnetic disk, any index pulse should be suppressed if the drive select signal assumes the prescribed state during the duration of that index pulse; otherwise, the leading edge of the index pulse would erroneously represents the angular position of the magnetic disk. Thus the disk drive circuitry is improved, typically by incorporating a flip-flop circuit, for suppressing the undesired index pulse and for permitting the delivery of the subsequently generated index pulses as long as the drive select signal remains in the prescribed state.

摘要： A circuit arrangement for a flexible magnetic disk drive having an index sensor for optically sensing an index hole defined eccentrically in the magnetic disk, with the index sensor putting out an electric index pulse of less than a predetermined duration each time it detects the index hole during the rotation of the magnetic disk. The index sensor is prone to put out invalid pulses of not less than the predetermined duration as a result of the displacement of the magnetic disk relative to the index sensor. For detecting the constant speed rotation of the magnetic disk on the basis of the valid index pulses only, the circuit arrangement comprises an index pulse spacing detector circuit for producing an index pulse spacing signal indicative of whether the spacings between the successive index sensor output pulses are less than a predetermined limit or not, a latching circuit for putting out a constant speed rotation signal in response to the index pulse spacing signal when the spacing between any two consecutive index sensor output pulses is less than the predetermined limit, and an index pulse duration detector circuit for inhibiting the production of the constant speed rotation signal by the latching circuit upon detection of an invalid pulse even if the spacing between this invalid pulse and the next index sensor output pulse is less than the predetermined limit.

摘要： An apparatus for data transfer with a magnetic disk having a diameter of, say, 86 millimeters, having a pair of transducer heads for data transfer engagement with the opposite surfaces of the disk mounted on a turntable driven directly by a disk drive motor. In order to hold the magnetic disk exactly level on the turntable for proper data transfer contact with the transducer heads, a leveling mechanism is provided whereby at least the turntable is made adjustably movable in its axial direction with respect to the frame of the apparatus, as by the manual turn of an adjusting screw or screws. In one embodiment, the turntable is movable with a drive spindle on which it is mounted coaxially and which forms an output shaft of the disk drive motor. In another embodiment, the turntable travels with the complete disk drive motor.
