Provided is a hinge type thinly configured integrated type key top in which the strength, durability, operability and other required conditions of a hinge portion are optimally designed assuring easy manufacturing and assembling as well as key input device and computer using the same. It is an integrated type key top in which a plurality of key tops are integrated with a peripheral frame portion. Each key top has in the vicinity of both ends of its specified one side a portion deformably connected to the frame portion via a hinge portion which extends approximately in a linear shape of a specified width and a specified thickness. The key top, the hinge portions and the frame portion are integrated with one another and made of a resin material, while the hinge portion has a thickness t (mm) and a total width w (mm) which are set so that 8.ltoreq.20t+w.ltoreq.14 is satisfied in a range of 0.25.ltoreq.t.ltoreq.0.6 and 2.ltoreq.w.ltoreq.10.

Integrated key top assembly

A small light-weight thin film magnetic head apparatus for a rigid disk or a floppy disc. The apparatus includes a magnetic head formed directly on a distal end of a suspension as a thin layer, one end of the suspension being supported by an arm. This magnetic head is very small-sized and light-weight and has a head gap in direct contact with a recording medium, increasing the recording density and the read/write speed. Because of its reduced weight of the thin film magnetic head, a remarkably improved degree of followability with respect to the recording medium can be achieved. A method of manufacturing this magnetic head apparatus is also disclosed.
