Abstract: A high-speed disk drive system that features significant performance improvements over previously available systems. By immediately fetching the data as soon as heads reach the destination cylinder, internally stripping the data across the surfaces and plurality of read/write heads on every surface the data transfer speeds many times depending on other characteristics of the system. By implementing plurality of read/write heads and internal parity surfaces or distributed parity blocks/zones the system achieves higher reliability (fault resistance) with head and surface fail-over fail-safing.

The slider generates an elevating force from air currents generated in a space between the first and second air bearing surfaces and the flexible rotating recording media.

Abstract: A read sensor with self-aligned low resistance leads and a method of making are provided. In the method a masking step has been eliminated by employing first, second and third protective capping layers in the construction of the read sensor and first and second lead layers. The first capping layer serves as a protective layer for the read sensor sites, the second capping layer protects low resistance lead layer portions during removal of the first capping layer from high resistance lead layer sites and then serves as a sacrificial layer during removal of spin valve material from the low resistance lead layer sites. The third capping layer protects the first and second lead layers during milling of low resistance lead layer material in field regions about the read sensor and first and second lead layers. The method aligns front edges of the low resistance lead layer portions with a rear edge of the read sensor so as to lower the overall resistance of the lead layers.

An air flow produced between the air bearing surfaces, and a magnetic disk creates an elevating force. A width of the first air bearing surface at the leading edge is controlled to be larger than a width at the trailing edge.
