Abstract:

Slider topology optimum design is a key method for achieving high storage density hard disk. A novel coding method of genetic algorithm for designing the topology of hard-disk sliders was proposed herein. The method took the depth of the cavity on the slider into consideration, which made the codes more complicated than the methods available and hence enlarges the space of the possible solutions. It is valuable for acquiring better solution and then getting the topology with better characteristics. By using this coding method, multi-layer slider can be designed which can meet the demands of the commercial hard disk. The effectiveness of the coding method was proved by a design example, and the whole procedure of the optimum design of slider topology was also demonstrated by the example.

Key words: slider, genetic algorithm, coding;optimum design
