Patent number: 11532322Abstract: The presently disclosed technology teaches integrating disc drive electronics into a transducer head. Decreased electrical transit times and data processing times can be achieved by placing the electronics on or within the transducer head because electrical connections may be made physically shorter than in conventional systems. The electronics may include one or more of a control system circuit, a write driver, and/or a data buffer. The control system circuit generates a modified clock signal that has a fixed relation to phase and frequency of a bit-detected reference signal that corresponds to positions of patterned bits on the disc. The write driver writes outgoing data bits received from an external connection to off-head electronics directly to the writer synchronized with the modified clock signal. The data buffer stores and converts digital data bits sent from the off-head electronics to an analog signal that is synchronized with the modified clock signal.Type: GrantFiled: October 22, 2021Date of Patent: December 20, 2022Assignee: SEAGATE TECHNOLOGY LLCInventors: Mark Anthony Gubbins, Robert William Lamberton, Robert Edward Weinstein, James Joseph Touchton

Patent number: 10008223Abstract: A read sensor having a bearing surface and an antiferromagnetic (AFM) layer recessed from the bearing surface. The read sensor includes a synthetic antiferromagnetic (SAF) structure over the AFM layer. The SAF structure includes a recessed lower pinned layer, an upper pinned layer, a reference layer and a stabilization feature. The stabilization feature may include deliberate reduction of the antiferromagnetic coupling energy density between the upper pinned layer and the reference layer, so that it becomes lower than the first energy density of antiferromagnetic coupling between the upper pinned layer and the lower pinned layer. The stabilization feature may alternatively include an intermediate pinned layer between the lower pinned layer and the upper pinned layer. The intermediate pinned layer is antiferromagnetically coupled to both the lower pinned layer and the upper pinned layer, and at least a portion of the intermediate pinned layer is recessed behind the bearing surface.Type: GrantFiled: February 17, 2017Date of Patent: June 26, 2018Assignee: Seagate Technology LLCInventors: Alexey Dobrynin, Zhiran Wang, Kevin McNeill, Denis O'Donnell, Sameh Hassan, Marcus Ormston, Robert William Lamberton

Patent number: 8228632Abstract: A non-limiting embodiment of a magnetic writer has at least a write element having a write element tip and a conductive structure adjacent the write element. The conductive structure has at least two conductive elements positioned substantially parallel to one another and separated by an electrically insulating material. Each of the conductive elements carries a time-varying signal to generate an oscillating magnetic field from a displacement current between the two conductive elements, with the oscillating magnetic field being proximate the write element tip and extending parallel to the air bearing surface. A frequency of the oscillating magnetic field is a function of a frequency of the time-varying signal.Type: GrantFiled: May 20, 2009Date of Patent: July 24, 2012Assignee: Seagate Technology LLCInventors: Mark Anthony Gubbins, Alex Wong, Robert William Lamberton
