Write Through Drivers for Disk Drive Systems

摘要

Circuits and methods are provided for write through drivers in disk drive systems. A write through driver is a transceiver that includes a write driver circuit and a receiver circuit. The write driver drives a current signal to a write element through a first conductive interconnect. The write element writes data patterns to a magnetic hard disk in response to the current signal from the write driver circuit. The current signal returns to the receiver circuit through a second conductive interconnect. The return signal can be used for the diagnosis of write-safe conditions.
