1. A method of manufacturing a head slider, comprising the steps of:
forming a magnetizable layer on a surface of a substrate wafer having a thickness greater than a length of the slider;
cutting said wafer into a plurality of raw bars after forming said layer while said thickness of said wafer is still greater than said length of the slider;
supporting said plurality of raw bars by a supporting jig;
arranging dummy sections of said plurality of raw bars in a single direction;
forming air bearing surface patterns on air bearing surface faces of said plurality of raw bars by photolithography; and
removing said dummy sections from said plurality of raw bars after forming said air bearing surface patterns.
2. The method according to claim 1, wherein said plurality of raw bars have thicknesses greater than a length of said slider, and are supported by said supporting jig in a machining step.
3. The method according to claim 1, wherein said dummy sections of said plurality of raw bars are arranged on one side in said supporting jig.
4. The method according to claim 1, further comprising the step of cutting at least one of said plurality of raw bars so as to form the slider.
5. The method according to claim 1, further comprising the step of removing the dummy sections before cutting into at least one of said plurality of raw bars.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A disposable diaper having a longitudinal axis, a first waist region, a second waist region, and a crotch region interposed therebetween, the disposable diaper comprising:
a backsheet;
a permeable topsheet joined to the backsheet, the topsheet having an upper body-facing surface and a lower surface, wherein the permeable topsheet comprises two Z-folds parallel to the longitudinal axis;
an absorbent core disposed intermediate the backsheet and the topsheet; and a plurality of temperature change elements disposed on the topsheet parallel to and spaced apart from the longitudinal axis, wherein the temperature change elements comprise permeable layers formed by the topsheet, impermeable layers formed by impermeable members disposed within the two Z-folds and interposed between the topsheet and the absorbent core, and a temperature change substance disposed on the topsheet, wherein urine deposited onto the temperature change elements can penetrate through the topsheet in a z direction to the impermeable members and wherein the impermeable members prevent urine from passing completely through the temperature change elements in the z direction and support the movement of urine in an x-y plane to wet the temperature change substance.
2. The disposable absorbent article as defined in claim 1, wherein the temperature change substance is interposed between the topsheet and the impermeable members.
3. The disposable absorbent article as defined in claim 1 wherein the impermeable members of the temperature change elements are elastically foreshortened.
4. The disposable absorbent article according to claim 1, wherein the two Z-folds further comprise two elastic members disposed along outside edges of the two impermeable members.
5. A disposable diaper having a longitudinal axis, a first waist region, a second waist region, and a crotch region interposed therebetween, the disposable diaper comprising:
a backsheet;
a topsheet joined to the backsheet;
an absorbent core disposed intermediate the backsheet and the topsheet; and
a temperature change element disposed on the topsheet along the longitudinal axis, the temperature change element includes a permeable layer having a body facing surface, a temperature change substance having a negative heat of solution and responsive to contact with urine to absorb heat and being disposed on the permeable layer, and an impermeable layer partially wrapped around the permeable layer such that longitudinal edges of the impermeable layer stop short of meeting, leaving a center portion of the body facing surface of the permeable layer exposed; and wherein the temperature change substance is disposed on the body-facing surface of the permeable layer in parallel regions covered by the longitudinal edges of the impermeable layer.
