Abstract: A read/write head for reducing flying height in a disk drive apparatus includes a write transducer for storing data on a storage medium, a read transducer for reading data from the storage medium, and read and write heater elements configured so that during read/write operations, heat dissipated in the read heater element is greater than heat dissipated in the write heater element. A control pad in the head receives current supplied to the read and write heater elements during read and write operations. During the write operation, protrusion of the read/write head attributable to the write transducer and the write heater element is greater than a protrusion of the head attributable to the read heater element. During the read operation, protrusion of the read/write head attributable to the read heater element and the read transducer is greater than a protrusion of the head attributable to the write heater element.

Abstract: A hybrid storage device comprises at least one storage disk, a disk controller configured to control writing of data to and reading of data from the storage disk, a non-volatile electronic memory, and a bridge device coupled between the disk controller and the non-volatile electronic memory. The disk controller comprises a plurality of high-speed serial interfaces. In one embodiment, the high-speed serial interfaces include a first high-speed serial interface configured to interface the disk controller to a host device, and a second high-speed serial interface configured to interface the disk controller to the non-volatile memory via the bridge device. The non-volatile memory may comprise a flash memory, and the bridge device may comprise a flash controller. The disk controller may be implemented in the form of an SOC integrated circuit that is operative in a plurality of modes including a hybrid mode of operation and an enterprise mode of operation.

Abstract: Servo control signals and data content associated with two different devices, such as a hard disc drive magnetic head and a digital video disc laser may both be processed without substantial loss of data or control signal errors using a single controller.
