摘要：
A slider of a magnetic disk device has a main body and a protecting layer coated on the main body. The protecting layer has first flat surface which faces the magnetic recording surface of the rotatable disk and which extends in a tangential direction of the disk when the slider is located adjacent to the magnetic recording surface of the disk. The contact region of the first surface is in contact with the magnetic recording surface of the rotatable disk. Thus, a frictional force produced between the magnetic recording surface and the first flat surface is reduced, and the damage to the magnetic recording surface can be prevented. According to the present invention, the damage to the magnetic recording surface of the disk can be prevented, and the variation in distance between the magnetic recording surface and the magnetic head can be remarkably reduced. As a result, the recording density of data recorded on the magnetic disk can be increased.
