Title:
DATA RECORDING DEVICE FOR MAGNETIC CARD
Document Type and Number:
Japanese Patent JPS6236782
Kind Code:
A
Abstract:
PURPOSE:To prevent the generation of jitters with the record data to be written to a magnetic card by latching temporarily the record data sent from a CPU through a data latch means and then transmitting the record data in the from of the write data in synchronization with a reference clock signal. CONSTITUTION:A controller 10 includes a read data processing part 11a which processes the signals read out of a read head 9a and converts them into the data and a write head driving part 11b which excludes the jitters out of the record data drives a write head 9b. Then the controller 10 processes the output data sent from the part 11a in accordance with the ON/OFF states of switches SW1-SW4 respectively. While a CPU 13 processes the actuation of a display part 2, the actuation of a motor driving part 12 of a feed motor 4 and the data delivered from a host CPU, etc. via input/output ports PB4-PB7. Furthermore a data latch means is formed with a D type flip-flop 15 together with a data recording means formed with the part 11b and the CPU 13 respectively.
