Title: Magnetic recording and reproducing device
Inventor: SEKIYA MASATAKA
IPC: H04N5/783
Filed: 1983-09-07
Abstract: PURPOSE:To prevent the horizontal deflection of a reproduced picture during switching of a reproduction mode by providing a reference signal generating circuit to produce a reference signal of a normal reproduction mode and a reference signal of variable speed reproduction mode respectively. CONSTITUTION:A reference signal generating circuit 21 produces a reference signal RP1 for phase comparison with a head control signal SP1 in a normal reproduction mode and a reference signal RP2 for phase comparison with a head control signal SP2 in a variable speed reproduction mode. The switching is carried out between signals RP1 and RP2 by a changeover switch 24 together with the switching between normal and variable speed reproduction modes. Thus a phase difference can be eliminated between signals SP1, SP2 and signals RP1, RP2 in a switching mode. This prevents the horizontal deflection of a reproduced picture when the switching is carried out between the normal and variable reproduction modes.

Abstract: PURPOSE:To form a combined part to small size, by forming a small-thickness annular plate part to an internally peripheral part of a fitted hole in a circular disc, equipping a sloped surface for the axial center in a shaft and tightening the disc and the shaft through a bolt under a condition in which the small-thickness annular plate part is elastically deformed for the sloped surface. CONSTITUTION:An internal peripheral edge of a fitted hole 11a is partially cut in the large-thickness direction, and a small-thickness annular plate part 11b, in length l to the radial direction and thickness t, is provided to a circular disc 11. On the other hand, a sloped surface 12b for the axial core is formed in an annular flange part 12a of a shaft 12, and the fitted hole 11a of the disc 11 is fitted to the shaft 12 and tightened by a bolt 13 in such a manner that a point end of the small-thickness annular plate part 11b are butted and adapted to the sloped surface. In this way, the relative displacement to the radial direction at high speed rotation is restricted to prevent generation of unbalance, and a problem relating to vibration can be solved, then a stable rotational characteristic can be obtained.

Abstract: PURPOSE:To enable exact tracking, by providing a servocontrol driving system which drives a driving coil by the off-track signal outputted from an optical head and a servocontrol driving system which drives a moving mechanism by the off-track signal. CONSTITUTION:A differential amplifier 30 is inputted with the two signals from a bisecting photodetector 28 via preamplifiers 30A, 30B, and outputs the off- track signal DELTAr according to the difference between the two signals. The 1st phase compensation circuit 31A is used for preventing the oscillation of the 1st servocontrol driving system, and compensates the phase to prevent the rotation of the phase of the signal DELTAr outputted from the amplifier 30. The 2nd phase compensation circuit 32A prevents the oscillation of the 2nd servocontrol driving system. If the gain ratio between the 1st amplifier circuit 31B of the 1st servocontrol driving system and the 2nd amplifier circuit 32B of the 2nd system is larger than the gain of the 2nd amplifier circuit 32B like, for example, 1:3, the greater part of the eccentricity generated in one turn of an optical disc 1 can be compensated by the linear motor 4 driven by the driving signal of the circuit 32B.

Abstract: PURPOSE:To provide a pulverized body having superior dispersibility, capable of producing a high density green compact, and excellent in sintering characteristics by specifying the mean particle size and the particle size distribution of a pulverized body by using a medium agitation mill. CONSTITUTION:In a pulverized body, the mean grain size of powder is regulated to <=0.6mu and also the particle size distribution of powder is regulated so that the particles having particle sizes two or more times larger than the mean particle size are >=7wt.%. IN order to produce the pulverized body, grinding is carried out by the use of a medium agitation mill while regulating the diameters of balls to <=1mm and using the same grinding liquid medium as that used at the time of the wet forming of powder. For example, a slurry prepared by premixing the calcined powder of lead- based piezoelectric ceramics with butyl acetate (grinding liquid medium) and dispersant is introduced into a medium agitation mill and subjected to grinding by the use of balls (0.4mm diameter) as well as an agitating device made of zirconia ceramics. Subsequently, the resulting powder dispersed in the grinding liquid nedium is subjected to wet forming and the resulting green compact is sintered, by which sintered compact can be obtained.

Abstract: PURPOSE:To improve recording or reproducing characteristics by removing a motor out of a base to attach the motor to the tip of an arm coupled weavably to the base and therefore easily attaching and detaching an optical disk to and from a rotor. CONSTITUTION:A optical disk 7 hits a guide pin 10 and is put on a table 3 of a rotor 5. Then a solenoid 26 is powered. Thus an arm 12 is turned down at the side of a base 1 and the axial center of a spindle 22 is set on the axial center of the rotor 5 when a center hole 4 is fitted to a projected part 23. While a tapered pressing part 25 presses the fringe of a circular hole 24 and therefore the center of the disk 7 is set on the axial center of the rotor 5. Thus a motor 21 is driven to revolve the spindle 22 and the rotor 5 together in a body for data processing. Then a carrier 6 can be moved to a position close to the center of the disk 7 since the base 1 does not include the motor 21. As a result, the memory capacity of the disk 7 is increased and the recording/reproducing characteristics are improved.
