Abstract: PURPOSE:To generate a reference signal at arbitrary multiple speed corresponding to the change of the rotational speed of a rotary cylinder, by performing the arithmetic calculation of a value equivalent to a change quantity when the rotational speed of a rotor is changed from the rotational speed at a stationary state, and storing an arithmetic value in a register. CONSTITUTION:A delay quantity (PG shifter quantity), a dividing angle between each head, and a value representing a prescribed position are tabulated by an arithmetic circuit 119, and the value obtained by multiplying a tabulated value by the change quantity from the stationary value of the rotational speed of the rotary cylinder 601 is stored in the registers 108 and 109. In such way, it is possible to change the generated position of a timing signal at arbitrary N-multiple speed considering the PG shifter quantity and the dividing angle of the head, to a regular position.

Title: Loop test code detection circuit
Inventor: FUNAE HIDEAKI
IPC: G06F13/00
Filed: 1986-11-11
Abstract: PURPOSE:To reduce software and a consumed current by using comparators for a loop test code in common as a reference loop test code. CONSTITUTION:When a coincidence pulse shows up from the comparator COMP 1-1 without detecting the loop test code, a gate G1-1 outputs an OK pulse to step a counter CTR 1-3. A flip-flop F/F 1-2 is set, and simultaneously a counter CTR 1-4 is reset. The loop test code is a fixed pattern. However it is assumed to be inverted by 8kHz. Hence a differentiation circuit and a gate G1-5 detect the time when the loop text code is not detected and when initially the OK pulse is outputted. Due to that detection, a flip-flop F/F 1-3 is set, and it divides a clock 8K 1-1 by two. All types of loop test codes are compared only during hunting. After the loop test code is found, only that code is compared. Hence one type of circuit suffices.
