ABSTRACT:
A contact type magnetic disk apparatus includes a magnetic disk, a magnetic head slider, a plurality of contact pads, and a bounce prevention structure. The magnetic disk medium has a liquid lubricant applied to a predetermined film thickness on its surface. The magnetic head slider has a magnetic head which records/reproduces information in/from the magnetic disk medium, while sliding in contact with the magnetic disk medium. The contact pads are arranged on the magnetic head slider so as to face the magnetic disk medium, and come into contact with the surface of the magnetic disk medium. The bounce prevention structure is arranged on the head slider including the contact pads to prevent the bounce of the magnetic head slider from the magnetic disk medium by using the meniscus force of the liquid lubricant. The bounce prevention structure has a predetermined spacing with respect to the surface of the magnetic disk medium when the contact pads come into contact with the magnetic disk medium.
