Title: Production of magnetic head
Inventor: KOMATSU SHINICHI
IPC: G11B5/235
Filed: 1981-08-17
Abstract: PURPOSE:To produce a magnetic head having high performance with high yield, by using the glass having a specific softening temperature in the manufacturing process of the magnetic head using the glass and then performing the glass bonding under the reduction of pressure. CONSTITUTION:The glass having a 535-610 deg.C softening temperature is used in the manufacturing process of a magnetic head which uses the glass of the adhesion of the members forming the magnetic head or for the filling at the worked part of these members. At the same time, the glass bonding is performed under the reduction of pressure. The adsorbed matters on the member surface of the magnetic head cause air bubbles into the glass, and these adsorbed matters are mainly the organic solvent stuck to the member of the magnetic head when it is washed, the water content contained in the air, etc. Thus the glass bonding is performed after removing completely these adsorbed matters in order to avoid the generation of air bubbles in the glass. The glass of a 535-610 deg.C softening temperature can perfectly prevent the generation of the air bubbles caused by the adsorbed matters.

Abstract: PURPOSE:To reduce the weight of the device, facilitate maintenance, and enhance the reliability, by constituting a position servo-system and providing weaving pattern generator, intending to prevent hunting of the servo-motor in the intermittent pulse pay-off circuit and increase the torch returning precision. CONSTITUTION:Angle control and weaving control are effected by commands from a teaching playback pulse distributor 106 and a weaving pattern generator 104, respectively. These commands are changed over in a circuit 105 to become a rotating direction command and a pulse command in a sign changing circuit 107. In order to change the rotating direction of the pulse motor without causing hunting, a certain time interval is preserved between these commands. In an intermittent pulse pay-off circuit, the vibrations in the hunting region are held down, and said output is passed through an insulating circuit 108 and a drive control device 101 to drive the pulse motor 112. A reducing gear 114 of a weaving unit 102 is small and light in weight, and the natural origin of the motor 112 may be determined by limit switch 115, pulse generator for precision origin 113, and origin processing circuit 116 thereof.

Abstract: PURPOSE:To swiftly stabilize the rotation state at a prescribed rotation speed by inhibiting a speed offset self-proving operation from resuming during a period from the completion of the speed offset self-proving operation to the commencement of a picture recording. CONSTITUTION:When a capstan motor 7 is rotated at the prescribed rotation speed by a transient operation at the time of starting up a speed offset self- proving speed control circuit 13 and the speed offset self-proving operation after releasing a pause of picture recording, a brake is applied to the capstan motor 7 by a phase difference pulse, and synchronization is performed between a reproducing CTL2 and a recording CTL1. On completion of this speed offset self-proving operation, the control circuit 13 is inhibited from resuming the speed offset self-proving operation, so that even when the capstan motor 7 is braked, frequency-voltage conversion characteristics of the control circuit 13 is still fixed to what have been set by the previous speed offset self-proving operation, and when the brake is released, the capstan motor 7 is controlled in speed by the characteristics to be under the state of rotation at the prescribed speed.

Title: Method and device for controlling light spot
Inventor: TERAO MASATOSHI
IPC: G11B7/1359
Filed: 1990-05-18
Abstract: PURPOSE:To control an image forming position in a tracking direction and to apparently reduce the amount of tracking error by providing a wedge-shaped prism in the front step of an objective lens, making a light flux obliquely incident to the objective lens and changing the inclination of the incident light to the lens while rotating the prism. CONSTITUTION:A center 105a of the light flux rectangularly incident to the lower surface of a wedge-shaped prism 15 is inclined by refraction and emitted from the prism 15. The size of this inclination is determined by the inclination of two surfaces in the prism 15, namely, a wedge-shaped angle is determined by a refraction factor. When the prism 15 is rotated, the inclining direction of the emissive light is changed and the center of the emissive light is rotated like a track 111. By this method, the prism 15 is not rotated once but turned by a fine amount and the inclining direction is changed by a fine amount. Then, this light flux is guided to an objective lens 13. Thus, an irradiating position on a disk 71 due to the lens 13 is moved in a tracking direction, namely, in the diameter direction of the disk 71 and an objective recording track is exactly irradiated with the light spot.

Filed: 1985-06-13
Abstract: PURPOSE:To prevent a reversing phenomenon which keeping an S/N and a frequency characteristic optimum by preventing the reversing phenomenon by an FM equalizer and correcting the deteriorated S/N and the frequency characteristic by a deemphasis.

An FM signal changing in this manner passes through a limitter 6 and is modulated by an FM modulator 7 and inputted to a deemphasis 8. When the characteristic of an FM equalizer 5 is changed so as to limit the sideband wave of the FM signal having the large modulating characteristic and easily producing the reversing phenomenon, the S/N of the demodulated video signal becomes better and the frequency characteristic becomes worse, so that the characteristic of the deemphasis 8 is changed correspondingly to the change of the characteristic of the FM equalizer 5.
