Abstract
Several embodiments of a method for manufacturing an optical assembly for use in an optical flying head are provided. The optical assembly may include a solid immersion lens and a magnetic coil. Techniques are provided for fabricating the solid immersion lens and the magnetic coil. Techniques are also provided for installing the optical assembly into a slider for the optical flying head. Other embodiments are described in which a solid immersion lens is installed in or is integral with a transparent slider. A magnetic coil may also be installed in these embodiments.

A method of integrating an optical assembly into a slider, comprising the steps of:
- (a) forming a substantially transparent slider having a void in a top surface thereof;
- (b) installing a partial solid immersion lens into the void;
- (c) placing an objective lens on or near the top surface of the slider;
- and
- (d) forming a mesa that extends from a bottom surface of the slider;
- such that the slider, the partial solid immersion lens, the objective lens, and the mesa maintain a fixed relationship with respect to each other.
A method of integrating an optical assembly into a slider, comprising the steps of:
- (a) forming a substantially transparent slider having a partial solid immersion lens formed therein;
- (b) placing an objective lens on or near a top surface of the slider;
- and
- (d) forming a mesa that extends from a bottom surface of the slider;
- such that the slider, the partial solid immersion lens, the objective lens, and the mesa maintain fixed distances from each other.
A method of integrating an optical assembly into a slider, comprising the steps of:
- (a) forming a substantially transparent slider having a void in a top surface thereof;
- (b) installing a partial solid immersion lens into the void;
- (c) placing an objective lens on or near the top surface of the slider;
- (d) placing a glass plate on a bottom surface of the slider;
- and
- (e) forming a mesa that extends from the glass plate;
- such that the slider, the partial solid immersion lens, the objective lens, the glass plate, and the mesa maintain a fixed relationship with respect to each other.

A method, comprising:
- (a) forming a substantially transparent slider having a partial solid immersion lens formed as an integral part thereof;
- and
- (b) placing an objective lens on or near a top surface of the slider at a fixed position relative to the slider;
- and
- d) forming a transparent mesa on a bottom surface of the slider in a position such that the partial solid immersion lens and the transparent mesa are aligned along an optic axis of the objective lens.
