Title: Reel rotary driving mechanism
Inventor: ITO MASAO
IPC: G11B15/26
Filed: 1990-03-09
Abstract: PURPOSE:To decrease the dispersion in a winding torque or a reel and to attain stable reel drive by inserting an elastic member between a rocking member of reel switching mechanism and a drive gear of a friction mechanism and directly driving the rocking member with the friction torque generated according to the drive of the driving gear. CONSTITUTION:The elastic member 33 is inserted between the rocking member 32 of the reel switching mechanism and the driving gear 30A of the friction mechanism to drive directly the rocking member 32 with the friction torque generated by the driving of the driving gear 30A. That is, the torque generated by the friction mechanism is not consumed by the drive of the rocking member 32 at the reel switching mechanism and transmitted directly to reels 25A, 25B via an idler gear 29. Thus, the dispersion in the torque transmitted to the reels 25A, 25B is only the dispersion in the torque by the friction mechanism. Thus, the dispersion in the winding torque of the reels 25A, 25B is less and stable reel drive is implemented and the mechanism is manufactured at a low cost.

Title: Magnetic recording device
Inventor: KIMURA HITOSHI
IPC: G11B21/10
Filed: 1988-03-09
Abstract: PURPOSE:To reduce power consumption and at the same time to improve vibration proofness by comparing the drop of the output level of a signal read out of a magnetic head with a reference voltage level to detect a track shift of a magnetic head due to vibration and compensating the holding current of a stepper motor only when a position shift is generated. CONSTITUTION:In a normal working state, the output e1 of an envelope detecting circuit 4 is larger than the reference voltage e0. At the same time, the output S1 of a comparator 5 is kept at '0' and the holding current is dropped for a stepper motor driver circuit 7. Then the output of an AGC incorporating amplifier 2 drops when the head position shifts with addition of external vibration while an amplification factor is kept to secure a fixed level of the output of the amplifier 2. When the output e1 drops less than the voltage e0, the output of the comparator 5 is equal to '1' and the circuit 7 has the full output of its holding current to reset the head position.
