Abstract

A magnetic head slider is described which has been formed by means of a corner-blending process so that head element wear and disk damage is minimized. The slider comprises side rails 1 and 2 having taper sections 3 at the leading end 4 and having a recessed area 5 between the side rails. At least one magnetic transducer element 6 is formed at the trailing end 7 of the slider. The leading end corners 8 of the slider are provided with a selected radius by making a change in the mask which is used for the etching process which defines the side rails 1 and 2 as is shown in Fig. 1. An alternate corner-blending process is shown in Fig. 2.

Novel Corner-Blended Slider and Process to Minimize Head/Disk Contact Stress

A magnetic head slider is described which has been formed by means of a corner-blending process so that head element wear and disk damage is minimized. The slider comprises side rails 1 and 2 having taper sections 3 at the leading end 4 and having a recessed area 5 between the side rails. At least one magnetic transducer element 6 is formed at the trailing end 7 of the slider. The leading end corners 8 of the slider are provided with a selected radius by making a change in the mask which is used for the etching process which defines the side rails 1 and 2 as is shown in Fig. 1. An alternate corner-blending process is shown in Fig. 2. In this case, the edge blended area is recessed a small distance d from the leading end 4 of the side rails 1 and 2 so that the edge blended area extends at least a predetermined distance from the leading end of the slider even when manufacturing tolerances are concerned. This slider design is usable in a magnetic disk storage system without causing damage to either the magnetic transducer element or to the magnetic disk.
