摘要： A data transfer apparatus is disclosed as typified by 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 (20) for rotating a record disk (18) unter the control of a disk motor drive circuit (46), a head motor (26) for incrementally moving a transducer head (22) radially of the record disk under the control of a head motor drive circuit (52), and a read/write circuit (64) for processing data read from, or to be written on, the record disk via the transducer head (22). 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 (46). In order to avoid waste of electric power, not only the disk motor drive circuit (46) but also at least either, preverably both, of the head motor drive circuit (52) and the read/wirte circuit (64) is connected to a common power line via a power control switch (100) which is closed only when the MOTOR ON signal is in a prescribed state to cause rotation of the disk motor.

The date select gates are under the control of a drive select signal supplied from the host equipment. The drive select signal has a first prescribed state for opening the data select gates to allow the passage of the desired data therethrough, and a second prescribed state for closing the date select gates. In order to avoid waste of electric power, at least one, preferably all, of the disk motor drive circuits (46), head motor drive circuit (52) and the read/write circuit (64) are connected to a common power line via a power control switch (100) which is closed only when the drive select signal is in the first prescribed state.

摘要： A data transfer apparatus for use with a replaceable dislike 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 record medium is not loaded in the apparatus, 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 record medium is loaded into the apparatus, 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.
