Title: Magnetic disk device
Inventor: ADACHI OSAMU
IPC: G11B5/265
Filed: 1987-05-14
Abstract: PURPOSE:To improve a reliability in a high recording density by providing a driving mechanism to move a magnetic head to arrange two gaps of a gap for recording and a gap for reproducing in parallel in the rotation direction of a recording medium only by the distance between two gaps. CONSTITUTION:A driving mechanism to move a magnetic head to arrange mutually in parallel two gaps of a gap 21 for recording and a gap 22 for reproducing at the interval of a physical distance in the rotation direction of a recording medium only by a distance Ld between two gaps 21 and 22 is provided. The recording of information to the recording medium is executed by the gap 21 for recording and the reproducing is executed by the gap 22 for reproducing. Thus, since the gap of a magnetic head is separated to the gap for recording and the gap for reproducing, the dimension, etc., of respective gaps 21 and 22 can be optimumly designed independently to match to respective conditions of the recording and reproducing and the mechanism to move the magnetic head is provided, and therefore, the gaps 21 and 22 come to the same position at the time of the recording and at the time of the reproducing viewed from the recording medium. Thus, in a high recording density, a stable and highly reliable recording and reproducing can be executed.

Title: Method and apparatus for counting contact output
Inventor: KUMASAKA TORU
IPC: H03K21/02
Filed: 1985-05-30
Abstract: PURPOSE:To attain sure count of operating number of times of a contact by counting an off-time of a contact signal from the end of a main contact signal and extending the main contact signal over a period until the count time reaches the setting time. CONSTITUTION:When a contact signal E composing of a main contact signal A and a chattering signal B is applied, the signal E is inverted (1) into a signal F and fed to a clock input terminal C of an FF circuit 2. The circuit 2 is set when the signal F rises and a set output G is inverted to an H level. Since the output G is fed to an AND gate 5 together with the signal F and a clock pulse CP, the pulse CP is sent as an output H only at the L period after the signal A. The signal H is counted by a counter 6 and its count value is fed to a decoder 7. The decoder 7 generates an output signal I by detecting the coincidence of the H signal generated from a predetermined output terminal of the counter 6. The signal B is ended when the signal I is generated. Thus, the effect of chattering is avoided.
