Title: Floating type magnetic head
Inventor: MURAI MASAMI
IPC: G11B5/187
Filed: 1987-08-19
Abstract: PURPOSE:To drastically reduce a friction coefficient, to prevent a recording medium from being flawed and to obtain a highly reliable head by applying the same lubricating film as that of a recording medium to the sliding face of a floating type magnetic head. CONSTITUTION:The same lubricating film as that of the recording medium is vapor-deposited on the sliding face of the floating type magnetic head against the recording medium by a resistor heating method. The thickness of the lubricating film is set up to 80-120% the lubricating film of the recording medium under the consideration of balance with the film strength of the recording medium. Since the static friction coefficient between the magnetic head and the recording medium can be drastically reduced, the mechanical deterioration of the recording medium can be suppressed. Since glass is exposed to the sliding face especially in case of a composite head, the generation of head crush due to the lacking of glass can be prevented. Consequently, a highly reliable head can be obtained.
