Abstract
A magnetic read/write head assembly has a slider including a first and a second insulation films formed on the both surfaces of a distal end portion of a suspension arm, the first and the second insulation films being formed by a sputtering technology. The suspension arm has a generally thin plate configuration having a neck portion for serving a function similar to a gimbal spring for permitting freedom of motion of the slider. A small number of constituent parts, a small size and weight of the head assembly can be obtained for achieving a low flying height and a high recording density performance.
