Abstract
A method of manufacturing a head suspension assembly for mounting a head slider on a suspension includes an irradiating light step, acquiring position information step and head slider mounting step. The irradiating light step is the step of irradiating light on a protective film and a marker at an incidence angle θ. The acquiring position information step is the step of acquiring position information of the marker by measuring reflected light from the protective film and that of the marker. The head slider mounting step is the step of mounting the head slider at a predetermined position of the suspension by using the difference of the intensity of reflected light from the protective film and that of the marker.
Claims8
A method of manufacturing a head suspension assembly for mounting a head slider on a suspension, comprising the steps of:
- irradiating light on a protective film and a marker of the head slider at an incidence angle θ;
- acquiring position information of the marker of the head slider by measuring reflected light from the protective film and that of the marker;
- mounting the head slider at a predetermined position of the suspension by using the difference of the intensity of reflected light from the protective film and that of the marker, wherein
- the head slider has a device part for reading information from a medium or writing information to a medium, a body part to be a substrate for forming the device part, and a protective film and a marker formed on an air bearing surface opposite to the medium surface, and
- when light is irradiated on the protective film and the marker, intensity of reflected light from the protective film and that from the marker are different.
A head slider comprising:
- a device part for reading information from a medium or writing information to a medium;
- a body part to be a substrate for forming the device part;
- and
- a protective film and a marker formed on an air bearing surface opposite to a medium surface of the body part, wherein
- the marker is lower than a front air bearing surface arranged on a leading end side of the air bearing surface of the body part.
