Title: Magnetic head supporting mechanism
Inventor: INAGAKI TATSUHIKO
IPC: G11B5/49
Filed: 1992-06-03
Abstract: PURPOSE:To provide an excellent recording/reproducing at the time of exciting vibration by providing the rotative center of a rotary mechanism on the almost vertical line of the weight center of a head assembling body, making a distance from the flow-in end of a sliding surface to the rotary center larger than a horizontal distance from a flow-out end to the rotary center and thereby improving durability. CONSTITUTION:A magnetic disk 1 is brought into contact with a head slider 10 by the load weight W of a load spring, the disk 1 is rotated and information is recorded and reproduced. A friction force muN is generated by a contact force N between the slider 10 and the disk 1. The center of the contact pressure is generated on a position shifted by muh (h is the height of the slider) toward the flow-in side from a P point. Therefore, the distribution of the contact pressure is almost uniform over the front surface of the sliding surface. Then, the mass (m) of the slider 10 is positioned at centroid. A rotary center P is positioned on the same straight line as the centroid and the mass (M) of an arm 13 is connected to it by a gimbal spring. When a vibration is excited to the device with the acceleration of (alpha), inertia force of malpha and Malpha are applied to the slider centroid and an arm centroid respectively. But since the slider centroid and the rotary centroid are on the same straight line, the slider is slided without a pitching motion.

Title: Motion detector
Inventor: ITO KAZUHISA
IPC: H04N19/196
Filed: 1990-05-31
Abstract: PURPOSE:To prevent drop-out disturbance of a vertical edge part without degrading the picture quality by providing a motion sensitivity converting part which multiplies large one of the current motion signal and the motion signal of the preceding line by a small coefficient and multiplies the other by a large coefficient and adds the multiplication results to obtain a motion signal. CONSTITUTION:Data is stored in a ROM 12 to generate such table that smaller one of motion signal data D1 of the just preceding line from a line memory 9 and current motion signal data D2 directly coming from a motion detecting part A is not selected but larger one of data D1 and D2 is multiplied by a coefficient K1 and the other is multiplied by a coefficient K2 and addition data of these multiplication results is selected. That is, the line memory 9 and the ROM 12 constitute a motion sensitivity converting part D which discriminates magnitude relations between data and multiplies them by coefficients to covert the sensitivity of motion data. Since motion data of the line of 1H before is multiplied by the coefficient, its influence is reduced to prevent the degradation in picture quality.
