Seagate Assigned Three Patents

Multipiece deck for HDD
Seagate Technology LLC, Cupertino, CA, , has been assigned a patent (8,797,679) developed by four co-inventors for a “multipiece deck for hard disk drive.“

The co-inventors are Wolfgang Rosner, Burnsville, MN, Timothy Edward Langlais, LMN Hany Michael Gross, Eden Prairie, MN, and Joseph H. Sassine, Lakeville, MN.

The abstract of the patent published by the U.S. Patent and Trademark Office states: “An apparatus is provided, including a base-deck floor; a base-deck frame, overlying the base-deck floor; a top cover, overlying the base-deck frame; and an affixing means operable to attach the base-deck frame to the base-deck floor, wherein the base-deck frame is operable to be fastened to both the base-deck floor and the top cover to provide a housing for a hard disk drive. A method is also provided, including assembling at least a portion of a hard disk drive assembly on a base-deck floor; affixing a base-deck frame to the base-deck floor; and securing a top cover to the base-deck frame.”

The patent application was filed on March 5, 2013 (13/784,838).

Adaptive seek latency
Seagate Technology LLC, Cupertino, CA, has been assigned a patent (8,797,675) developed by Mark Larry Birtzer, Rosemount, MN, and Raye Abdoulie Sosseh, Minneaplis, MN, for “an adaptive seek latency.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “The disclosure is related to systems and methods for adaptive seek latency in a rotating storage device. In one example, a servo control circuit can be configured to determine a seek latency and provide the seek latency to another controller or control circuit that is configured to implement the seek latency. Further, the servo control circuit can calculate the seek latency based on a measurement of a variable condition of a device and the servo controller can adjust the seek latency as the condition varies. In some examples, the variable condition may include power measurements, temperature measurements, a fault rate, other conditions, or any combination thereof. Also, different algorithms for calculating the seek latency may be implemented based on a selected goal of the system, such as power savings or reduced head vibration.”

The patent application was filed on Feb. 23, 2012 (13/403,821).

Disk-synchronized loading/unloading of magnetic head
Seagate Technology LLC, Cupertino, CA, has been assigned a patent (8,767,337) developed by four co-inventors for systems and methods “for disk-synchronized loading/unloading of magnetic head.”

The co-inventors are Craig Smith, Santa Clara, CA, Bernhard Hiller, San Jose, CA, Stan Shepherd, Morgan Hill, CA, and Erhard Schreck, San Jose, CA.

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Systems and methods from loading/unloading a data head for a disk drive provide for more efficient use of disk space. A method of loading/unloading a data head for a disk drive comprises determining a disk phase of a spinning disk arrangement, determining a loading/unloading position based on the disk phase, and loading or unloading the data head on or from, respectively, the spinning disk arrangement based on the determined disk phase. The determining a disk phase may be based on zero crossing of voltages for a three-phase motor associated with the spinning disk arrangement.”

The patent application was filed on April 17, 2007 (11/736,441).
