摘要： The array pitch `d` between the control electrode strips with respect to the conveyed direction of the recording medium is determined based on the order of applying operating voltage, the resolution `x` of the image with respect to the conveyed direction, and the number `m` of the control electrode strips. Illustratively, in order to obtain a particular resolution `x` with respect to the conveyed direction of the paper, by taking into consideration the reduction in dot interval or conveyed distance by the conveyance of the recording paper, the array pitch `d` between the control electrode strips with respect to the conveyed direction of the recording medium is set as the dot distance produced when the paper is not moved, plus the above reduction. This can be written as d=(n+1/m)/x where n is a natural number.

摘要： A motor stop control device for stopping a motor rapidly. The motor control includes a pulse generator for generating a pulse signal having a pulse width which is in relation to the speed of the motor, a CPU, and a drive for driving the motor. When a motor stop command signal is produced when the motor being rotated forward, CPU operates the drive to produce a counter drive torque, and, at the same time, CPU starts to compare the pulse width of the present pulse signal with that of the previous pulse signal, and produces a signal when the pulse width of the present pulse signal becomes shorter than that of the previous cycle. When the signal is produced, the drive stops to produces the counter drive torque.

摘要： A disk recording checking method in which recording is performed on a disk having radially different recording tracks each divided circumferentially into a plurality of sectors. The method employs a continuous writing device for continuously writing data onto a predetermined number of the sectors, and a continuous checking device for checking the data, while continuously reading the data from the predetermined number of the sectors. The method utilized checks both the number of errors in each code sequence and the total number of errors in each sector to determine if the data in the sector is valid.

摘要： A signal processing device comprises a comparator, a first reference signal generating unit, a second reference signal generating unit and reference signal controller and switch which is switched when the data head data of the input signal is detected by the controller. In the case when the content of the input signal is a clock producing data, the reference signal generated in a rapid process of the first reference signal generating unit is entered in the comparator, and in the case when the content of the input signal is a reproduction data, the reference signal generated in a slow process of the second reference signal generating unit is entered in the comparator so as to be compared with the input signal.
