    • A data transfer apparatus for use with a replaceable disklike record medium such as a flexible magnetic disk having data storage tracks thereon, comprising a disk drive motor for imparting rotation to the record medium, and a head transport motor for transporting a transducer head or heads radially of the record medium so as to enable the transducer head or heads to access the individual data storage tracks on the record medium for data transfer therewith. Also included is a control and drive circuit for controllably energizing the head transport motor. When the disk drive motor is out of rotation, the control and drive circuit holds the supply voltage of the head transport motor zero, or lower than its normal operating voltage for head transportation, for saving power. Then, as the disk drive motor is set into rotation, the control and drive circuit applies the normal operating voltage to the head transport motor preparatory to the commencement of data transfer, thereby automatically recorrecting the head position on the record medium.

    • An electric control system for an apparatus for writing and reading data on and from a flexible magnetic disk under the control of host equipment such as a central processor unit having an associated controller. The control system includes a time setting circuit responsive to stepping pulses, by which the magnetic head is transported from track to track on the disk, for determining an access time to be elapsed from the moment the head starts to be transported from any track on the disk to any other track thereon to the moment the head becomes stably positioned on the new track. Connected to the time setting circuit is an index pulse suppressor circuit which suppresses any index pulse, indicative of the rotation and angular position of the magnetic disk, that is generated during each access time and which permits the delivery to the host equipment of the subsequent index pulses that are generated after the lapse of the access time. A read data suppressor circuit is also provided which inhibits the delivery to the host equipment of any data read from the disk either during the access time or from the moment the transducer head starts moving toward a new track to the moment the first index pulse is generated after the lapse of the access time. Thus the host equipment is conditioned to commence the writing of data only after the head is stably positioned on each new track.

    • A floppy disk drive which, together with one or more like devices, is daisy chained to host equipment comprising a central processor unit and an associated controller. Each disk drive comprises a disk motor for rotating a record disk under the control of a disk motor drive circuit, a head motor for incrementally moving a transducer head radially of the record disk under the control of a head motor drive circuit, and a read/write circuit for processing data read from, or to be written on, the record disk via the transducer head. The host equipment produces, among other control signals, a MOTOR ON signal for the on/off control of the disk motor via the disk motor drive circuit. In order to avoid waste of electric power, not only the disk motor drive circuit but also at least one, preferably both, of the head motor drive circuit and the read/write circuit is connected to a common power line via a power control switch which is closed only when the MOTOR ON signal is in a prescribed state to cause rotation of the disk motor.

    • A flexible magnetic disk drive is disclosed which has a disk drive motor for imparting rotation to the magnetic disk under the control of a "motor on" signal, and a stepping motor capable of stepwise rotation in response to stepping pulses for transporting a transducer head or heads radially of the magnetic disk for track to track accessing. Connected to the transducer heads for processing data transferred between them and the magnetic disk, a read/write circuit is connected to a supply terminal via a switching transistor. This switching transistor has connected to its base a switch control circuit for holding the switching transistor nonconductive when the disk drive motor is out of rotation and when the stepping motor is in rotation, and for holding the transistor conductive at least during the progress of data transfer between the transducer heads and the magnetic disk. Preferably, the switch control circuit is further adapted to hold the power control switch open from the moment the disk drive motor is set into rotation to the moment the speed of rotation of the disk drive motor builds up to a prescribed percentage of a normal speed at which data transfer is effected between the transducer heads and the record medium.

    • A data transfer system of the type including a disk drive for selective use with flexible magnetic disk cartridges of first and second storage capacities (e.g. 1 MB and 4 MB), the first storage capacity being less than the second storage capacity, a host computer, and a controller for controlling the operation of the disk drive under the direction of the host computer. The controller is factory preprogrammed to discriminate between unformatted disk cartridges of the two different storage capacities as either of the two types of disk cartridges is loaded in the disk drive. The program is such that, in response to the first of a series of formatting commands at the first storage capacity from the host computer, the controller causes the disk drive to write track format for the second storage capacity on a preassigned track (e.g. inmost track) on the disk and then immediately to read the track format. If the retrieved track format contains errors, it follows that the loaded disk cartridge is of the first storage capacity. Accordingly, the controller proceeds to format the disk cartridge at the first storage capacity. If the retrieved track format does not contain errors, on the other hand, then the loaded disk cartridge is of the second storage capacity. Thereupon the controller signals the host computer to that effect.
