Abstract: Damaging head crashes are prevented in a disk drive system by providing a specially chosen RC network between the head position control servo (12) and the head actuator (10). The values of the RC network are chosen in conjunction with the servo output voltage so that, without detracting from head access time, the maximum head velocity will be limited to a value which will prevent damaging head crashes even when a fault occurs in the system.

Abstract: A disk storage system comprising a rotatable disk (10), a cooperating magnetic head (18), positioning apparatus (24, 26) for positioning the head at different radial positions of the disk for reading and/or writing data on the disk, a baseplate (16) for supporting the above, and control circuitry (33) for preventing oscillation build-up in the baseplate from deleteriously interfering with system performance. The control circuitry is constructed and arranged to control the timing of head positioning operations so as to inhibit the reinforcement of baseplate oscillations.

Abstract: An aqueous coating composition forming a magnetic coating layer. The composition is improved over prior art magnetic coatings by the inclusion of a colloidal emulsion of a lubricant, such as, for example, a member selected from the group consisting of aliphatic and aromatic stearates, silicone oils, perfluoro alkyl polyethers and fluorinated fluids.
