Title: Tracking controller
Inventor: ITOI TOSHIKI
IPC: G11B7/085
Filed: 1989-04-05
Abstract: PURPOSE:To prevent a disk from being damaged by an objective lens by stopping or inhibiting a track jump operation, when displacement of the objective lens exceeds a set value. CONSTITUTION:At the time of executing intermittently a track jump operation, displacement of an objective lens 22 is detected by a component being near a DC of a voltage of a tracking driving use coil 30, and when this displacement exceeds some set value, the track jump operation is stopped or inhibited. In such a way, in an objective lens driving device, it is prevented that a movable part for holding the objective lens comes into collision with a stopper of a fixed part, and since it does not occur that the focus-servo is detached, it can be prevented that the objective lens hits against a disk and the disk is damaged.

Title: Tape slack detecting device
Inventor: MISAO IKUO
IPC: G11B15/00
Filed: 1980-06-25
Abstract: PURPOSE:To ensure assured detection for the slack of a traveling tape, by detecting the degree of inclination for reduction change of the rotating speed of a reel motor that drives a tape reel. CONSTITUTION:For instance, in a quick forward mode, the frequency signal is generated from a frequency generator 10 in accordance with the rotational frequency of a reel motor 2 of take-up side that is turning in a high speed and in the take-up direction. Then the fall differential output showing the degree of inclination of the frequency signal is delivered to a waveform shaping circuit 21 through a frequency- voltage converting circuit 13 and a differentiating circuit 20. The circuit 21 obtains the slack detection signal to actuate a stop controlling circuit 17 in case the reduction speed of the motor 2 exceeds the critical value. In such way, the slack of a traveling tape can be detected in an assured way.

Title: Rotary arm type actuator
Inventor: FUNAI KIYOSHI
IPC: G05D3/00
Filed: 1982-05-21
Abstract: PURPOSE:To improve the control performance for head positioning, by setting a magnet assembly close to a housing with no contact between them and therefore decreasing the number of vibration modes of the housing with reduction of the vibrating amplitude. CONSTITUTION:A housing 2a and a magnet assembly 7a are fixed to a base 11 independently of each other. Therefore the mass of the housing 2a is reduced by an amount equal to the assembly 7a. This also decreases the degree of freedom. As a result, the number can be reduced for the vibrating modes of the housing 2a along with reduction of the amplitude. With the frequency response characteristics of a conventional rotary arm type actuator, three resonances of about -5dB amplitude size exist among 1,400-1,700Hz. This deteriorates the head positioning control characteristics. In this example, however, just a peak of about -10dB amplitude size exists with 1,700Hz, and the peak is small at the resonance point less than -10dB. Thus the vibrating characteristics can be greatly improved.
