Fault-tolerant directory cache controller

The invention discloses a fault-tolerant directory cache controller for the problem that a conventional directory cache is poor in fault tolerance and low in reliability, and cannot meet the requirements of a spatial environment or a complicated electromagnetic environment. The fault-tolerant directory cache controller comprises four identical directory cache bodies, a directory access bypass, a directory access crossbar switch, an access crossbar switch and a configuration register.

Current-assisted magnetic recording write head with wide conductive element in the write gap

A current-assisted magnetic recording write head has an electrically conductive layer in the write gap between the write pole and the trailing shield. Electrical circuitry directs current between the write pole and the trailing shield, through the conductive layer in the write gap. The current through the conductive layer generates an Ampere field substantially orthogonal to the magnetization in the write pole to assist magnetization switching of the write pole. The conductive layer is wider in the cross-track direction than the trailing edge of the write pole and may extend beyond the write pole side gaps so as to be in contact with both the side shields and the trailing shield. The conductive layer may have substantially the same along-the-track thickness across its width or it may have a thicker central region at the write pole trailing edge and thinner side regions.
