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: 6898033Abstract: A procedure for estimating bit error rate (BER) for disc media in a disc drive is disclosed. Initially, the BER estimation procedure writes random data to specified tracks on the disc media. The procedure then reads the specified tracks over predefined time intervals to determine a BER for the disc media at the termination of each interval. Using the determined bit error rates, the procedure extrapolates the BER values to generate a decay graph representative of a BER slope over the time period comprising the time intervals. The decay graph is then used to estimate BER for the disc media at a predetermined time, such as the end of the expected life of the disc drive.Type: GrantFiled: December 20, 2001Date of Patent: May 24, 2005Assignee: Seagate Technology LLCInventors: Robert Edward Weinstein, Elias Glavinas, Timothy Ray Mason, Randall Lee Pacek

Patent number: 6445519Abstract: The method and apparatus herein identifies baseline instability events occurring within a magneto-resistive head. The method commences by capturing a signal average amplitude of a signal emanating from the head. The signal average amplitude is used to set a threshold, the transcendence of which indicates a baseline instability event. Finally, each baseline instability event is counted. The apparatus includes an envelope detector, which captures the signal average amplitude. A comparator unit, operably connected to the envelope detector, uses a threshold based upon the signal average amplitude, and sets a flag whenever the head signal exceeds the threshold. Finally, a counter unit increments its count total each time the flag is set. The counting unit may employ timing control, meaning that it will only increment its total if the flag is set when a clock signal triggers the counter unit to test the flag to decide whether or not to increment.Type: GrantFiled: December 28, 1999Date of Patent: September 3, 2002Assignee: Seagate Technology LLCInventors: Robert Edward Weinstein, John Charles Harig, III, Michael Dominic Schaff
