Patent number: 8969840Abstract: Systems (and methods therefor) for generating EUV radiation that comprise an arrangement producing a laser beam directed to an irradiation region and a droplet source. The droplet source includes a fluid exiting an orifice and a sub-system having an electro-actuatable element producing a disturbance in the fluid. The electro-actuatable element is driven by a first waveform to produce droplets for irradiation to generate the EUV radiation, the droplets produced by the first waveform having differing initial velocities causing at least some adjacent droplets to coalesce as the droplets travel to the irradiation region, and a second waveform, different from the first waveform, to dislodge contaminants from the orifice.Type: GrantFiled: August 5, 2014Date of Patent: March 3, 2015Assignee: ASML Netherlands B.V.Inventors: Chirag Rajyaguru, Peter M.

Patent number: 8238051Abstract: Real time monitoring inconsistent operations in a hard disk drive, wherein the hard disk drive comprises a magnetic disk, a controller and a channel clock. A timing signal from the channel clock is measured in real time in the controller. Time intervals between sector identifier marks of the magnetic disk are detected using the timing signal from the channel clock during reading and writing operations of the hard disk drive in the controller. An inconsistency in the drive operations is detected in the controller based on changes in the time intervals between the sector identifier marks is detected during operation of the hard disk drive. The detection of the inconsistency in the drive operations is responded to.Type: GrantFiled: December 8, 2009Date of Patent: August 7, 2012Assignee: Hitachi Global Storage Technologies, Netherlands B.V.Inventors: Peter M.

Patent number: 7933085Abstract: Magnetic disk drive systems and associated methods are described for verifying a spacing between read/write heads on a slider and a magnetic recording disk during end-user operation. An operating power applied to heating elements in the slider controls the spacing due to thermal protrusion. While in end-user operation, the operating power is temporarily increased to a test power to decrease the spacing. The test power is then evaluated to determine if contact between the read/write heads and the magnetic recording disk is detected. If contact is not detected, then the spacing due to the operating power is determined to be adequate. If contact is detected, then the operating power is recalibrated.Type: GrantFiled: March 31, 2008Date of Patent: April 26, 2011Assignee: Hitachi Global Storage Technologies Netherlands, B.V.Inventors: Peter M.

Patent number: 7660068Abstract: In a method of pre-contact detection and active damping of air bearing vibrations in a hard disk drive, a slider is isolated from ground. The slider is then capacitively coupled with a hard disk of the hard disk drive via a thermal fly-height control (TFC) heating element. An alternating current (AC) signal is applied to the slider via the TFC heating element to control the amplitude of the slider.Type: GrantFiled: September 18, 2008Date of Patent: February 9, 2010Assignee: Hitachi Global Storage Technologies Netherlands B.V.Inventors: Peter M.

Publication number: 20100007976Abstract: A magnetic head is described herein. A method for manufacturing the magnetic head comprises determining a protective distance for a protective structure to extend beyond an element in a direction toward a disk, layering the protective structure, and removing material from the protective structure to obtain approximately the protective distance. The protective distance is from an element end to a protective structure end. The protective distance is determined based on a magnetic head profile. The thickness of the protective structure is based on pole-tip recession.Type: ApplicationFiled: July 9, 2008Publication date: January 14, 2010Inventors: Peter M. Baumgart, Wen-chien D.

Patent number: 7359138Abstract: In method of feedback control for active damping of slider air bearing vibrations in a hard disk drive slider, a slider is isolated from ground. A velocity signal is acquired from the slider. The velocity signal is filtered to acquire a vibration signal. The vibration signal is adjusted in amplitude to achieve an amplitude adjusted vibration signal. The amplitude adjusted vibration signal is applied to the slider to actively dampen vibrations in the slider.Type: GrantFiled: November 29, 2005Date of Patent: April 15, 2008Assignee: Hitachi Global Storage Technologies Nethelands, B.V.Inventors: Thomas R.
