Title:
ROTARY TYPE MAGNETIC RECORDING DEVICE
Document Type and Number:
Japanese Patent JPS6117273
Kind Code:
A
Abstract:
PURPOSE:To record the information having a high reliability by recording the information in a floppy disk, and thereafter, checking it by the second window signal generated from a VFO circuit at the time of WRITE VERIFY. CONSTITUTION:A VFO circuit 30 outputs a clock signal (the first window signal) synchronizing with binary information, and an optional value of a decoder. A window signal generating circuit 50 has a flip-flop 51 for inputting a window signal, and it is constituted so as to generate the second window signal whose timing is different from that of the first window signal. A write detecting circuit 60 has a flip-flop 62 which is set by a write control signal (h) at the time of reproduction after recording the information, and an (n)-acid counter 61 for counting an IXIDEX signal by (n) times, and resetting the flip-flop 62 by this output signal. A switching circuit 70 is constituted so that AND circuits 72, 72' are controlled by an output of the write detecting circuit 60.
