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 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.
摘要翻译：公开了一种用于步进电机的驱动方法和系统，该步进电机通常在环形布置的相应定子极上具有若干组四相绕组，以及具有恒定圆周间隔的几个交替的N极和S极的转子。通常，通过单相或双相驱动模式顺序地激励绕组，以使转子以增量旋转。为了将转子停止在所需的角度位置，四个相绕组中的任何一个或两个在正常方向上被激励，以将相关联的定子极或极极化成一个极性，以吸引转子的相反极中的一个。此外，所指示的一个或两个绕组的两侧的其它相绕组在反向方向上被激励，如通过电容器的放电，相关的定子极的相应的极化相反。因此，极化为不同极性的定子极可能使转子在所需角度位置的正向定位。

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： A control system for a disk drive operating under the control of a host system for data transfer with a magnetic disk medium. The host system provides a signal indicative of whether the disk drive is in operation in a read-only mode or in a write-only or read-and-write mode. During operation in the write-only and read-and-write modes, the control system inhibits the delivery to the host system of both read data and index pulses during, for example, a disk start-up time, and access time and a transducer loading time, because the data recovered from the disk medium during such times may be inaccurate, inviting inaccurate writing. However, during operation in the read-only mode, the control system constantly permits the delivery of read data and index pulses to the host system with a view to the curtailment of the average read access time.

摘要： An apparatus having a pair of magnetic transducer head assemblies for data transfer contact with the opposite faces of a flexible magnetic disk. One of the head assemblies has its disk engaging surface disposed at an angle to the normal plane of the magnetic disk in order to hold the disk engaging surfaces of both head assemblies in proper data transfer contact with the magnetic disk in spite of its wobbling movements during rotation. The disk engaging surface of that one head assembly slants away from the normal disk plane in a direction that can be anywhere between a radially inward direction of the magnetic disk and a tangential direction of a notional circle drawn concentrically on the magnetic disk, the tangential direction being upstream of the magnetic disk with respect to its predetermined direction of rotation. As the other head assembly is gimbaled and sprung against the slanting head assembly via the intervening magnetic disk, both head assemblies can be held in proper data transfer engagement with the disk despite its undulations in both radial and tangential directions.

摘要： A disk apparatus using a CLV method is provided in which disk apparatus a power consumption is reduced by providing a power save mode in which an operation of a head driving system is stopped during a standby state. The disk apparatus uses a constant linear velocity method by which method a recording/reproducing operation of information on a disk is performed while the disk is rotated at a variable speed so that the linear velocity of the head relative to the disk is maintained to be constant. A disk driving unit rotates the disk, and a head driving unit drives the head. A linear velocity controlling unit controls a rotational speed of the disk so that the linear velocity of the head relative to the disk is maintained to be constant. A constant rotational speed controlling unit rotates the disk at a constant rotational speed. A switching unit switches a control of the disk driving unit to be performed by either one of the linear velocity controlling unit and the constant rotational speed controlling unit. A stopping unit stops an operation of the head driving unit while the disk driving unit is controlled by the constant rotational speed controlling unit.
