Abstract

A new, micro contact recording head was designed, fabricated and evaluated. The developed head contains two newly designed elements: a suspension using a `remote centered compliance (RCC)' mechanism and a slider pad with a `pocket- equipped' surface texture. The suspension made of polyimide was fabricated by an ultraviolet laser beam machining; the slider pad made of glass was done by a fast atom beam etching. The RCC suspension with 20 μm thick notches attained a nose-up attitude of the head, improving modulation of read back signal to ±5%. The pocket-equipped sliding pad with a few 10 nm deep holes prevented a heavy friction, reducing friction coefficient to 0.2. For evaluations, a test bench for head sliding operation under a scanning electron microscope using a micro force sensor with a resolution of 0.5 μN is also developing. When we realize a more durable lubricant film on the sliding pad and a lower normal pressure down to the disk, the micro contact recording head will practically enhance a recording performance by minimizing tribological problems.
