DISK CONTROLLER WITH MILLIMETER WAVE HOST INTERFACE AND METHOD FOR USE THEREWITH
First Claim
Patent Images
1. A disk controller for use in a disk drive having a disk, the disk controller comprising:
- a read/write channel module for writing write data to and reading read data from the disk;
a host interface module that couples the disk controller to a host device, the host interface module including;
a millimeter wave transceiver coupled to wirelessly communicate read commands, write commands, the read data and the write data between the disk controller and the host device over a millimeter wave communication path in accordance with a host interface protocol;
a protocol conversion module coupled to convert the read commands, the write commands and the write data from the host interface protocol and to convert the read data to the host interface protocol; and
a host module coupled to decode the read commands and the write commands from the host device, to process the read commands to retrieve the read data from the disk via the read/write channel and to process the write commands to write the write data to the disk via the read/write channel;
a memory that stores operational instructions;
a processor, operably coupled to the memory, the host interface module and the read/write channel, to perform at least one disk control function in accordance with the operational instructions.

Abstract
A host interface module couples a disk controller of a disk drive to a host device. The host interface module includes a millimeter wave transceiver that is coupled to wirelessly communicate read commands, write commands, the read data and the write data between the disk controller and the host device over a millimeter wave communication path in accordance with a host interface protocol. A protocol conversion module is coupled to convert the read commands, the write commands and the write data from the host interface protocol and to convert the read data to the host interface protocol. A host module is coupled to decode the read commands and the write commands from the host device, to process the read commands to retrieve the read data from the disk drive via a read/write channel and to process the write commands to write the write data to the disk drive via the read/write channel.
