IPC: G11B5/127
Filed: 1989-09-19
Abstract: PURPOSE:To prevent the peeling of nonmagnetic material substrates by butting nonmagnetic plates for reinforcement against the outer side faces of the nonmagnetic material substrates which are superposed on each other, heating and thermocompression bonding while these plates are pressurized from the 4 direction. CONSTITUTION:Plural pieces of the nonmagnetic material substrates 4 are superposed on each other and the nonmagnetic plates 21 for reinforcement consisting of crystalline glass, ceramics, etc., are butted against both the outer side faces orthogonal with the superposition direction thereof.

Abstract: PURPOSE:To obtain a cheap positioning device for a magnetic head by finding the distribution of the number of sectors obtained with a detecting means at every positioning position, and providing a positioning means which performs the positioning of the magnetic head at the average position of the distribution. CONSTITUTION:An error Le exists between the track position written on a magnetic disc 20 and the position of a magnetic head 5 sent from a stepping motor 1, and to minimize the error, after the magnetic head 5 is sought to a step position corresponding to an objected track 21 with the stepping motor 1, the magnetic head 5 is moved in the sequence of scanning numbers from the inner circumference of the magnetic disc 20 to the outer circumference in one direction in order, and the number of sectors read with the magnetic head 5 at each pulse position are counted. The number of sectors that can be read is reduced as the magnetic head 5 is moved away from the center position of a track on which data have been written, and it is possible to minimize the error between a normal track position and the position of the magnetic head 5 by positioning the magnetic head 5 to the average pulse position. Thereby, the cheap positioning device for the magnetic head can be obtained.

Title: Multi-path detection circuit
Inventor: MIURA MASAMI
IPC: H04B17/309
Filed: 1988-09-28
Abstract: PURPOSE:To properly detect a multi-path disturbance by providing a PLL circuit locked with a pilot signal when its level is larger than a prescribed level, amplifying an output voltage of a low pass filter, rectifying it and outputting a detection signal. CONSTITUTION:At a condition that a pilot signal is in a prescribed level or over in the presence of a multi-path disturbance, the pilot signal is subjected to phase modulation. Then the output voltage of a low pass filter 12 is changed from a zero level and locked. Thus, the output voltage VD of a prescribed level is fed from a synchronizing detector 21 to a detection section 3, which is activated. Then the detection signal VD outputted from the detection section 3 changes from a zero level and the presence of multi-path disturbance is detected. On the other hand, in a weak electric field where the pilot signal is smaller than a prescribed level, since the PLL circuit 1 is in the unlocked state, the erroneous detection of multi-path disturbance is prevented.
