けた構成となっている。As this type of magnetic head slider, for example,
There is one described in No.-569. As shown in FIGS. 4 and 5, this magnetic head slider includes a slider body 1 disposed facing the surface of a magnetic disk, which is a magnetic recording medium, and is mounted at the center of the rear of the slider body 1. A magnetic head 2 is provided, and three rails 3, 4.5 extending in the longitudinal direction and consisting of an inclined surface portion and a flat surface portion are provided in parallel on the surface of the slider body 1 facing the magnetic disk surface; The slider body 1 is attached to a support system (not shown) via a support system attachment surface 6 provided on the back surface thereof.

。In the above conventional technology, as shown in FIG. 5, the center of gravity G of the slider body 1 is shifted toward the magnetic disk 7 by an amount Q from the point of application A of the force during the seek operation, and the force due to the theta direction acceleration during the seek operation is is transmitted from the slider support system to the slider body 1 via the support system mounting surface 6. The slider body 1 is levitated by the action of air bearings formed on the surfaces of the rails 4 and 5, but since the acceleration generated in magnetic disk drives with the latest high-speed access mechanism is as large as several tens of G, the slider body 1 levitates. This results in a decrease in quantity. If the flying height of the slider body 1 decreases significantly, there is a risk that the slider body 1 and the magnetic disk 7 will come into contact and cause a crash. This trend was reflected in the ``Electronic Design 5'' (Electronic Design 5) on March 1, 1980.
A similar problem occurs in the thin-film magnetic head slider disclosed in J.D. 5, March, 1-, 1980).
