Title: Write circuit for floppy disk device
Inventor: OKUBO TOSHIKI
IPC: G11B5/09
Filed: 1989-07-27
Abstract: PURPOSE:To reduce a peak shift and to write write signals of respective period with optimum resolution by varying a write current writing a delay signal into a floppy disk in accordance with the output level of a current signal. CONSTITUTION:A holding circuit 3 outputs the current signal 11 holding the value of a discrimination signal 10 when it is pulse-inputted by the delay signal 9. A flip flop 4 switches the output state of respective output terminals Q and the inverse of Q and supplies the current to a coil C1. The write current at that time is decided by a variable constant current circuit 6 in accordance with the current signal 11. Thus, resolution when the signals of respective period are written can be improved, and the peak shift can be reduced by supplying the write current optimum for the period of the write signal to the magnetic head 12.

Abstract: PURPOSE:To enhance printing quality, by storing correction data for correcting the variation in the beam receiving intensity of the laser beam in a scanning direction generated by a lens and correcting laser output intensity during scanning. CONSTITUTION:A laser diode driving control circuit is equipped with a laser driving circuit 40 for performing the ON/OFF control of a laser diode on the basis of an image signal and an output control circuit 42 detecting the output intensity of laser beam and outputting a reference voltage signal for holding said output intensity to reference intensity to the laser driving circuit 40. Data for correcting the variation in beam receiving intensity generated by the passage of laser beam through a lens is stored in a correction data memory means at every scanning position, and the reference voltage signal from the output control circuit 42 is corrected at every scanning position by an output correction circuit. Therefore, the beam receiving intensity of laser beam at each scanning position on a photosensitive drum becomes a constant value over an entire scanning width and printing density becomes uniform.
