Latest Patents
One of McMurtrey's latest patents is titled "Writing reference patterns in a disk drive using back EMF based timing signals compensated for repeatable variation therein." This invention provides an apparatus for writing reference patterns on a data storage disk of a disk drive. The disk is rotated by a spindle motor, and a back EMF sense circuit generates a sequence of zero crossing signals from the back EMF sensed on the windings of the spindle motor. This sequence defines a corresponding sequence of zero crossing periods of time. A Phase Locked Loop (PLL) circuit generates a timing signal in response to the comparison of a feedback signal to the zero crossing signals. The PLL circuit compensates for repeatable variation among the sequence of zero crossing periods, ensuring that the timing signal is substantially independent of these variations. Additionally, a recording pattern generator writes reference patterns on the disk in response to the timing signal as the disk rotates.
Another significant patent is the "Test rack adapter for hard disk drive." This adapter allows two or more hard disk drives to conduct self-testing in a single test rack slot. The testing can be individually controlled for the various HDDs in a slot, and Peltier cell devices or other cooling or heating devices can be controlled to achieve individualized temperature control for HDDs in the test rack slot.
