Figure 3 A is a plan view, B is a cross-sectional view, and Figure 3 A to E are used to explain the case where conventional magnetic heads are placed on the magnetic disk with distance from both sides with respect to the center line of the spindle. A is a plan view, B is a cross-sectional view, D and E are views showing changes in flying height, and FIG. 4 is a cross-sectional view for explaining the flying of the magnetic head according to the present invention. In the figure, 1 is a magnetic head, 11 is a magnetic disk,
12 is a groove.

Claims

[Scope of utility model registration request]

Attached to the carriage of the magnetic disk drive 2
The magnetic head is a twin-body type magnetic head having two air bearing surfaces, and the magnetic head is placed on the disk at a distance on both sides with respect to the center line of the spindle that rotates the disk of the magnetic disk device, and the magnetic head is placed on the disk by rotation of the disk. In order to correct the sun balance of the flying height of each magnetic head, the twin-hulled type is characterized by a configuration in which the width of the flying surface of each magnetic head is controlled independently to keep the magnetic head and disk parallel. magnetic head.
