Abstract

PURPOSE:To reduce the power consumption by locking a magnetic head in a stop state by a permanent magnet of a voice coil motor, when the magnetic head is attached to a swing arm and is stopping at a prescribed position by a stopper member. CONSTITUTION:When a magnetic head 38 is positioned in the innermost periph ery of a disk 39, one end of the outside peripheral part of a coil 34 abuts on a stopper member 42 and a movement of the head 38 is in a stop state. In this case, a magnetic member 41 attached to a swing arm 31 through a member 40 is attracted by a permanent magnet on this side of a voice coil motor 33. As a result, the force in the inside peripheral direction of the disk 39 works on the arm 31, and the coil 34 being in the end part of the arm 31 is pushed against the stopper member 42. By this pushing force, the stop state of the movement of the head 38 is locked. In such a way, a lock mechanism can be obtained easily and at a low cost.

(Problems to be Solved by the Invention) In recent years, with the spread of magnetic disk drives, there has been an increasing demand for their compactness, lower price, and lower power consumption. Under these circumstances, providing a locking mechanism that requires a large number of parts as shown in Figure M5 will hinder miniaturization and cost reduction. Further, the conventional locking mechanism requires electric power to release the lock, so there is a problem in that it hinders the reduction in electric power.

At this time, the magnetic member 41 attached to the swing arm 31 via the member 40, as shown in FIG.
In front of the voice coil motor 33, it is attracted in the direction of arrow F by the magnetic force of the permanent magnet 35. When the magnetic member 41 is attracted in the direction of arrow F, a force in the inner circumferential direction of the disk 39 acts on the swing arm 31, and the coil 34 at the end of the arm 31 is pressed against the swing member 42. This pressing force locks the stopped state of movement of the magnetic head 38.

On the other hand, when recording/reproducing data, the disk 39
is rotated in the direction of arrow B by the driving force of a spindle motor (not shown). When the disk 39 reaches steady rotation, the magnetic head 38 flies due to the air bearing effect. When the magnetic head 38 floats, the coil 34 of the voice coil motor 33 is excited.

In this case, the coil 34 moves the magnetic head 38 to the disk 3.
It is excited by receiving a current in the direction of movement in the data area direction (outer circumferential direction) of No. 9. Due to this current 0 (supply), a force acts on the magnetic member 41 in the direction opposite to the direction of arrow F, and the locked state is released.

Further, when the operation is stopped or the power is cut off, a current is supplied to the coil 34 in the direction of moving the magnetic head 38 to the C8S area (innermost circumference) of the disk 39. This current supply causes the magnetic head 38 to move toward the swing arm 31.
The coil 34 moves toward the C8S area (innermost circumference) of the disk 39 through the stopper member 42, and one end of the outer circumference of the coil 34
It stops at the position where it touches, that is, the C8S area. At this time, as described above, the magnetic member 41 is attracted in the direction of arrow F by the magnetic force of the permanent magnet 35, and its stopped state is locked.

The stopped state of movement of 8 can be locked. In this case, the only component primarily required for this locking mechanism is the magnetic member 41. Therefore, it can be constructed more easily and inexpensively than conventional locking mechanisms that require a large number of parts, thereby making it possible to make the magnetic disk device more compact and lower in price. Further, since the locked state can be released without requiring special power for unlocking, power consumption can also be reduced.
