High track density has been achieved by adopting an H, controller with a feed-forward compensator using adaptive filter theory in a sector servo system. In applying the H,,, control theory, a state-space model of an augmented plant was constructed considering the input location of the disturbance. M

✦ Synopsis
The paper describes the development of an expert system for failure analysis and disposition of hard disk drives (ESHDD). A working prototype was implemented in the form of a run-time version and tried out on the production floor.
Besides providing logical and accurate consultation, the developed expert system can also be used as a teaching aid for new staff, and serves as an excellent documentation of the test procedures involved in hard disk testing.

This paper deals with a fuzzy drive expert system for an auto-cruise car. This system consists of four rule sets such as environment recognition rules, driving control rules, learning-evaluation rules, and management. meta-rules. The structure c'f those rules is hierarchical. The fuzzy drive expert
This paper considers the modeling and compensator design for Self-ServoWriting (SSW) process in disk drives. An Iterative Learning Control (ILC) based scheme is established to deal with radial error propagation and improve the quality of written tracks. In the proposed scheme, a feedback controller
