Title:
NEGATIVE PRESSURE COMPOSITE LEVITATION MAGNETIC HEAD AND MANUFACTURE THEREOF
Document Type and Number:
Japanese Patent JPH04167280
Kind Code:
A
Abstract:
PURPOSE:To shorten the time of forming a negative pressure generating surface and to enhance an accuracy by providing a recess for forming the negative pressure generating surface formed deeper than a step on a positive pressure generating surface, and a negative pressure generating surface forming member filled in the recess. CONSTITUTION:A recess 3 of a square groove shape having a predetermined depth from a flat surface 1b of a slider body 1 as a positive pressure generating surface 2 and opened at the flat surface 1b of the body 1 at the side of a medium and the end face 1c at the side of moving the medium is formed at the surface 1b of the body 1 at the side of the medium. A negative pressure generating surface forming member 4 is filled in the recess 3, its medium side part is removed to a predetermined step later, and a negative pressure generating surface 5 is formed in a step-down shape. Thus, the time of forming the negative pressure generating surface is shortened, and forming dimensional accuracy can be simply enhanced.
