Title: Rotary head type magnetic recording and reproducing device
Inventor: SUZUKI YUTAKA
IPC: G11B15/467
Filed: 1987-03-30
Abstract: PURPOSE:To perform a program searching reproduction at a constant tape traveling speed, independently of the length of a tape by obtaining a voltage corresponding to the revolving speed of a rotary head by means of a pulse generating means and a converting means, and supplying the said voltage to a circuit to control a tape travel. CONSTITUTION:The pulse generating means generates the pulse of a frequency, corresponding to the revolution of the rotary heads 15a, 15b. The converting means converts the frequency of the pulse into the voltage and outputs it. the controlling means supplies the output voltage of the converting means to the circuit to control the tape travel, after the tape 10 starts traveling at the time of a program searching reproduction. Thus, the tape traveling speed at the time of the program searching reproduction can be made constant, and the revolution of the rotary head comes stable, and the tape traveling speed can be made constant independently of the tape length.

Abstract: PROBLEM TO BE SOLVED: To surely prevent faulty fixing from occurring by an easy operation, by providing a set temperature changing means changing set temperature based on an instruction by a set temperature change supporting means and a set temperature deciding means deciding the set temperature changed, SOLUTION: At the time of detecting that an operator pushes a push-button SW25 in order to change fixing target temperature (S102), a fixing target temperature changing mode is started (S103). Then, a target is set to the lowest temperature first (S104) and test printing is executed by one sheet in such a state (S105). The operator confirms the result of the test printing. and waits in the same state if the fixing is insufficient. Namely, when a push-button SW26 is not pushed, the fixing is judged to be insufficient, so that the target is incremented by a fixed value (S107) and the test printing is executed once more. When the operator judges that the fixing is sufficient, he pusheds the push-button SW26 (YES at S106), and the fixing target temperature is decided in accordance with the target value at that time.

Title: Positioning controller for magnetic head
Inventor: KITAMURA SHUNJI
IPC: G11B21/10
Filed: 1988-03-31
Abstract: PURPOSE:To accurately obtain an off-track quantity even when different off- track quantities are generated in magnetic heads by setting the reference voltage of an A/D conversion means at an appropriate value corresponding to a result detected by a magnetic head switching detection means. CONSTITUTION:When a head number is switched and designation to read/write another magnetic head is issued, the head number from a host system is transferred to a comparator 21. The comparator 21 compares a preceding head number stored in a head register 23 with the head number designated newly, and outputs a discrepancy signal E to a CPU20. The CPU20 outputs data capable of setting the reference voltages of an A/D conversion circuit 15 and a D/A conversion circuit 17 at a sufficiently higher value to a D/A conversion circuit 22. Therefore, the circuit 17 transfers comparatively large correction data from the CPU20 to a control circuit. Next, the CPU20 outputs the data to lower the reference voltages of the circuit 15 and the circuit 17 to the circuit 22. In such a way, it is possible to obtain the data with high accuracy corresponding to a small off-track quantity by the CPU20.
