させていた。Is Photo 2 a row of conventional magnetic disk drives? FIG. With respect to the disk 2 which is fixed to the disk drive motor 6 and rotates, the head 7 for recording and reproducing is fixed to the movable body 3 and rotates and reciprocates in the direction of arrow a]20 in the figure around the shaft 10i. ! The movable body drive motor consists of a magnetic circuit Ig8 and a coil portion 9, and the coil portion 9 is fixed to the movable head 3 and is electrically driven in the direction of the circular arrow 21 in the figure to access the head 7. Coil part 9 fixed to movable body 3
Buffer bodies 12 and 13 whose two sides are separate bodies, respectively.
By coming into contact with the disk 2, the movable range of the head 7 relative to the disk 2 is limited. During transportation, an electromagnet 35 (near) plunger is fixed to the body 1 to hold the movable body so that the movable body 3 does not move due to external shocks and damage the bed 7 and the disk 2. 36
When the power is not energized, the μ connecting dragon moves in the direction of the arrow head 37, and when the power is not energized, it engages with the protrusion 38 of the movable body 3 to hold and fix the movable body 3.

徴とする。A magnetic disk device of the present invention includes a disk drive motor, a disk that is fixed to the motor and rotates, a head that is fixed to a movable head positioning member and that moves approximately radially above the disk to perform recording and reproduction, and the disk. In magnetic disk IT, which is purchased from a drive motor, a disk, a head filling movable member, and a casing that seals the head, during transportation, an iron piece attached to the head positioning movable member and a mounting plate are attached to the outside of the casing. The movable member is locked in a fixed place by a magnet and a chisel.

ル部9に鉄片14を取シ付ける。外部からの衝撃が加わ
る輸送時Kti、筐体1外部に磁石15を取り付ける。FIG. 1 is a plan view showing an actual Is array of a magnetic disk device according to an embodiment of the present invention. An iron piece 14 is attached to the nine coil portion 9 which is fixed to the movable body 3. A magnet 15 is attached to the outside of the casing 1 during transportation when an external shock is applied.

に往復運動をして記録再生?:行う。Since the iron piece 14 is attracted in the direction of the arrow n by the magnetic force of the magnet 15, the movable body 3 is locked and will not move even if an impact is applied, and the head 7 and disk 2 will not be damaged. During operation, when the magnet 15 attached to the outside of the housing 1 is removed and the lock is released, the movable body 3 becomes free to rotate around the axis 1 ( ), and the movable body 11
The head 7 attached to the disk drive motor 6 is fixed to the disk drive motor 6 and makes a reciprocating motion in the direction of arrow I with respect to the rotating disk 2 for recording and reproduction. :conduct.

いう効果を有する。As described above, according to the present invention, since there is no dust source inside, there are no problems such as dust generation, and since the number of parts is reduced, assembly is easy and costs can be reduced. 'Also, there is no need to adjust the plunger mounting position during assembly, which reduces power consumption. Even when unlocking, there is an effect that it is only necessary to remove the magnet attached to the outside of the casing.
