Title: Method for assemblying magnetic head carriage for fdd
Inventor: AZUMA KENICHI
IPC: G11B21/02
Filed: 1985-02-27
Abstract: PURPOSE:To eliminate the need for skills in assembly work by temporarily fixing the carriage and an arm with an adhesive, then permanently fixing the two utilizing fastening tool, after positioning of an '0'-side magnetic head and '1'-side magnetic head is performed. CONSTITUTION:When fixing the carriage 2 and the arm 3, an instantaneous adhesive 17 is applied to the instantaneous adhesive application part A, and both two parts are temporarily fixed. The adhesive to be used for the temporary fixing exerts a resistant force sufficient to resist the revolutionary force applied during the work of permanent fixation with screws 5 i.e. a force that impairs the positional relation between said two parts. Because the permanent fixation utilizing the screws 5 is executed after the temporary fixation of the carriage 2 and the arm 3 with the adhesive 17, the positional relation between said two parts does not change, the permanent fixation can be achieved quickly and accurately. As a result, the assembly of the magnetic head carriage with stable quality and extremely excellent productivity can be achieved without any skill of the worker.

Title: Failure detector of encoder
Inventor: YAMAZAKI HIROSHI
IPC: H02P29/00
Filed: 1983-03-10
Abstract: PURPOSE:To prevent the secondary damage due to runaway of an encoder by providing a failure detector, thereby discovering the defect of the encoder in a short time. CONSTITUTION:The output of an encoder 7 is applied to a speed feedback circuit 4, and simultaneously inputted to a failure detector 8. When the output frequency fm of the encoder 7 decreases even if the encoder 7 becomes defective and a motor 1 is rotated, a comparator 3 judges that the rotating speed of a motor 1 is slow to cause the motor to run away. Since the frequency simultaneously decreases to cause the pulse to increase at the period at this time, the output terminal 9 of the detector 8 becomes H level. In this manner, the encoder failure can be detected.

IPC: G11B5/60
Filed: 1995-02-28
Abstract: PURPOSE: To make possible the recording of a high-transfer rate signal by a magnetic field modulation recording system. CONSTITUTION: A slider 7 which floats by receiving the air flow generated by rotation of a magneto-optical disk D in a disk mounting position is provided with recessed grooves 9 which open to the end face on the disk device mounting side. The air flow generated at the time of rotation of the disk, therefore, passes the inside of the recessed grooves 9 of the slider 7. Since this air contributes to the enhancement of the cooling effect of the slider 7, a head core 11 does not attain a high temp. and the magnetic characteristics of the head core 11 are maintained. The occurrence of the degradation in the recording efficiency is thus prevented.
