摘要： The invention concerns a disk file controller for the transfer of data from a parallel by bit interface to a serial by bit disk file interface.
A data channel has a data register (9), serializing and deserializing means (50 and 53) and a variable frequency oscillator to transfer parallel by bit data received by the register (9) from a DCI BUS OUT to be recorded serially by bit on a disk file. Alternatively the data channel receives serial by bit data read from a disk file and transfers it through the data register (9) in parallel by bit form to a DCI BUS lN. The several units of the data channel are controlled by a control register (28) supplied from a microprocessor (6). The microprocessor receives data selectively from the DCI BUS OUT and from the data register (9). Changes in format of the disk file data can be accommodated by the microprocessor (6) without need to change special purpose formatting hardware.

摘要： The invention concerns the transmission of data from a transmitting control unit to a disk file controller through an interface cable the length of which may vary from one installation to another thereby varying the propagation delay through the cable from one installation to another.
A SYNC IN signal from an AND gate (26) of the disk file controller is used to request data from the control unit. A SYNC OUT signal is returned by the control unit. A clock generator supplies bit timing signals BIT 0 to BIT 7 to a selector (24) and the selector issues a gating signal to an AND gate (31) to generate a SYNC IN signal at a selected one of the bit times as determined by a byte of control data contained in a register (22). The bit time is selected to account for the propagation delay of the interface cable such that the resultant SYNC OUT signal is returned at a desired bit time appropriate for recording data at a predefined location on a moving recording disk.
