Title: Head positioning system for disk device
Inventor: KOBASHI TETSUZO
IPC: G11B21/08
Filed: 1988-09-08
Abstract: PURPOSE:To prevent a head from run away and also from colliding by making the period for a bit of servo information on a guard band of the inner circumfer ence of the outer circumference of a disk recording medium shorter than that for a bit of servo information on a data recording area. CONSTITUTION:The inner circumferential guard band area 53 and the outer circumferential guard band area 54, which are provided on both sides of a disk surface in the radial direction of the data area 52, are written continuously with a repeating pattern of a servo information part 48, 49 and a gap 78 only. By this method, by detecting a DC erasure part and an addressing mark of the servo information part 48 and 49, a sector pulse 67 is outputted, and this period is outputted as a short period 81 of about (1/10)-(1/several tens) of a fixed period of the data area 52. By detecting this period difference, the guard band area can be rapidly detected, and the overshoot is reduced at the time of moving the head, thus preventing the head from run away and colliding.

IPC: G03G15/00
Filed: 1988-09-06
Abstract: PURPOSE:To connect more interlock signals to one analog port to perform discrimination control by collecting interlock signals and using an analog port instead of a digital port to input them to a CPU. CONSTITUTION:Plural interlock signals are detected with one analog port of the CPU to perform the control. That is, interlock signals inputted to an analog port Pa of the CPU 1 are different in level by turning-on states of respective switches. Consequently, the CPU 1 detects and discriminates levels of these interlock signals to detect switches which are turned on. Then, various required control of turning-off of a power source and a voltage power source, stop of a control signal, etc., is performed, and this state is displayed on a counter display part 2 with figures. Thus, plural interlock signals are connected by one analog port, and an inexpensive sure opening/closing detector is obtained.

Filed: 1986-09-26
Abstract: PURPOSE:To reduce steady power consumption by using 1st and 2nd kinds of amplifying elements which have mutually complementary operation characteristics like a p channel MOS transistor(TR) and an n channel MOS TR, and constituting two amplifying couples by connecting those two kinds of amplifying element in series. CONSTITUTION:Transistors p1 and p2 constitute a 1st current mirror and n1 and n2 constitute a 2nd current mirror. Then p3 and n3 are connected in series to form the 1st amplifying element couple. At the same time, p4 and n4 are also connected in the 2nd amplifying element couple. Then, a differential output is led out of the source side of the p3 and the source side of the n4. This differential output is led out through the output stage consisting of a couple of CMOS TRs p5 and n5 for output connected in push-pull relation. Consequently, currents which flow to the individual amplifying element couples (p3-n3) and (p4-n4) steadily are reduced to almost the same level of a CMOS type amplifier circuit.
