Abstract
A method is disclosed for constructing an ultra-low-flying-height slider for carrying a transducing head in a disc drive system including a rotatable disc. The method comprises removing material from an air bearing surface of the slider to create a channel at a likely location of contact with the rotatable disc and filling the channel with a low-friction, high-wear-resistance material. The channel is filled such that the air bearing surface is configured the same as the air bearing surface configuration prior to removing material.
Claims20
A method for constructing an ultra-low-flying-height slider for carrying a transducing head in a disc drive system including a rotatable disc, the method comprising:
- removing material from an air bearing surface of the slider to create a channel at a likely location of contact with the rotatable disc;
- and
- filling the channel with a low-friction, high-wear-resistance material such that the air bearing surface is configured the same as the air bearing surface configuration prior to removing material.
A method for constructing an air bearing slider, the air bearing slider carrying a transducing head above a rotatable disc in a disc drive system and the air bearing slider having a disc opposing face, the disc opposing face having an air bearing surface elevated above the disc opposing face, the method comprising:
- analyzing the air bearing surface to locate a plurality of contact points at a likely location of contact between the slider and the disc;
- forming a plurality of channels recessed from the air bearing surface, the channels formed approximately at the contact points;
- and
- depositing a low-friction, high-wear-resistance material in the channels such that an exposed surface of the low-friction, high-wear-resistance material lies in substantially the same plane as the air bearing surface.
