A large impact force is applied to the two magnetic heads due to the collision, resulting in damage to the characteristics of the magnetic head. Furthermore, repeated collisions may eventually lead to damage to the magnetic head. Furthermore, the impact force when the magnetic heads collide resulted in damage to the magnetic disk held between them.

ためである。1.2 illustrates an embodiment of the present invention. In the figure, the reference numeral 1 indicates a magnetic head, and this magnetic head 1 is attached to a head arm 3 via a gimbal spring 2. FIG. A portion of the head arm 3 corresponding to the gimbal spring 2 is an opening 3a. This is to ensure free deformation of the Jinnoi Jrespring 2.

When an upward external force is applied to the magnetic head 1 (one-plane head) as indicated by the arrow x in FIG. 1, the magnetic head 1 tends to be pushed upward. At this time, since the magnetic head 1 is attached to the gimbal spring 2 and is further elastically supported by the pressing pin 4C2 via the buffer member 5, it can be displaced upward in FIG. When the external force is removed, the buffer member 5 has a restoring force and returns to its original state by absorbing the impact force generated when it collides with the magnetic head 7 (zero-plane head) and relieving the impact force applied to the magnetic heads 1 and 7. Return to

で構成してもよい。In the above embodiment, a buffer member 5 is attached to the tip of the suppressing pinch 4, and the magnetic head is elastically supported via this buffer member. It is also possible to give elasticity by pasting an elastic material such as rubber to the pin 4, or the suppressing pin 4 itself may be made of an elastic member.
