INFORMATION RECORDER
Document Type and Number:
Japanese Patent JPH0721596
Kind Code:
A
Abstract:

PURPOSE: To provide a stable floating operation by detecting the levitating amount fluctuation of a slider with high sensitivity.

CONSTITUTION: A slider 5 to be levitated and slid on a magnetic disk 20 is provided with a force detecting probe 11 composed of a flexible cantilever 12, and inter-atom force, magnetic force or the gradient of them to be acted between the magnetic disk 20 and the force detecting probe 11 is detected. A vertical moving mechanism 4 is driven based on the detected inter-atom force or magnetic force so as to fix the levitating amount of the slider 5. Thus, the levitating amount fluctuation of the slider can be detected with high sensitivity and even with the levitating amount of 100nm or less, the stable levitating operation can be obtained.
