Abstract
An optical or magneto-optical (MO) head comprises a head formed of two main parts: a housing and a body. The housing supports optical and magnetic components to be secured to the slider, and the body provides an air bearing surface and further supports the housing. The housing includes a pattern of channels and grooves that retain the optical and magnetic components, and that can be produced with extreme accuracy, so that the cumulative tolerance of the head varies within a very tight range. The components are interlocked within, or secured to the slider in a self-aligned disposition, and do not become detached, even under extremely harsh operating conditions. In addition, the self-alignment feature significantly reduces, if not entirely eliminates the need to align certain components after they have been mounted onto the slider. The slider design enables the head to be mass produced and assembled.
