Patent number: 8738846Abstract: A file system-aware SSD management system including an SSD management module that incorporates both file system information and information related to the underlying physical solid-state storage media into its operations is described. Also described are related methods for performing data management operations in a file system-aware manner. By incorporating both file system and physical storage information, the system may achieve various advantages over conventional systems, such as enhanced I/O performance, simplified SSD firmware, and extended SSD lifespan. Moreover, by moving solid-state management functions above the firmware level, the system may enable the simultaneous management of a pool of multiple SSDs.Type: GrantFiled: October 14, 2011Date of Patent: May 27, 2014Assignee: Arkologic LimitedInventors: Kyquang Son, Ronald Lee, Henry C. Lau, Rajesh Ananthanarayanan

Patent number: 8516513Abstract: An optical disk cassette has a disk eject mechanism that ejects a disk such as a DVD or CD. The disk eject mechanism has pushrod, transfer and kick out portions. The pushrod portion slides relative to a side of the cassette case. Pivotally mounted within the case, the kick out portion pushes a disk to eject it from the case. The transfer portion translates pushrod motion to motion of the kick out portion. In a preferred embodiment, the disk eject mechanism is a unitary body, with pushrod, transfer and kick out portions made homogeneously as a single entity, the pushrod portion being a resilient joining elbow. In another preferred embodiment, the disk eject mechanism has a transfer portion that is a rack and a pinion. The rack extends from the pushrod portion and the pinion is attached to or formed as part of the kick out portion.Type: GrantFiled: January 6, 2010Date of Patent: August 20, 2013Assignee: Hitachi-LG Data Storage, Inc.Inventors: Kyquang Son, Ravender Goyal, Amir H. Torkaman, Jamie Nam, Michael Szelong, Paul R. Swan, Michael Umansky

Patent number: 8385163Abstract: A system for optical disc storage, writing and reading including a housing holding at least two optical disc racks and a plurality of read/write drives that may be positioned in line with the storage rack. A track spans the racks, (e.g., a parallel track is positioned between two racks). A shuttle mounted on the track allows transfer of discs from the racks to drives. The shuttle may allow for disc pass through, disc rotation, or have other structures for disc transport.Type: GrantFiled: January 6, 2010Date of Patent: February 26, 2013Assignee: Hitachi-LG Data Storage, Inc.Inventors: Ravender Goyal, Kyquang Son, Amir H. Torkaman, Jamie Nam, Kimhoe Pang, Richard Sharpe

Patent number: 8266642Abstract: An optical disk mechanism has a housing with at least one disk entry/exit aperture. A disk guide, such as a plate, is aligned with and guides an optical disk through the disk entry/exit aperture. Two beams rotatably support at least one roller and a drive mechanism. Flexing and biasing the roller towards the disk, the two beams maintain a rotational axis of the roller parallel to the disk and accommodate varying separation between the roller and the disk guide. The two beams are closely spaced and non-coplanar, and may be part of a double-beam mount. The double-beam mount attaches the two beams to the housing and to a frame, which positions the roller near the disk guide and the disk entry/exit aperture. Sliding the disk along the plate or other disk guide, the roller is reversible to drive the disk in or out through the disk entry/exit aperture.Type: GrantFiled: January 6, 2010Date of Patent: September 11, 2012Assignee: Hitachi-LG Data Storage, Inc.Inventors: Amir H. Torkaman, Michael Szelong, Kyquang Son, Ravender Goyal, Paul R. Swan, Michael Umansky

Publication number: 20110315577Abstract: An optical disk cassette has a cassette case with a disk retention device. A free end of the disk retention device acts upon an edge of the optical disk, opposably displacing during insertion and ejection of the optical disk. The device and disk are at equilibrium when the free end is displaced by the full diameter of the disk. When the disk is displaced in the insertion or ejection direction, the free end urges the disk in the insertion or ejection direction, assisting with the optical disk insertion or ejection respectively. Embodiments may have the disk retention device including one or more retainers. Each retainer may have a free end and opposing fixed end, and be flexible or have a flexible region. The free end slides along or otherwise contacts the circumferential edge of the optical disk, exerting a force upon it during optical disk insertion, retention and ejection.Type: ApplicationFiled: January 6, 2010Publication date: December 29, 2011Applicant: DataLane System, Inc.Inventors: Kyquang Son, Ravender Goyal, Amir H.

Patent number: 6976146Abstract: A system and method for emulating conventional block appended checksums on storage devices that generally do not support such checksums in a block is provided. A grouping of data sectors with one or more checksum sectors is generated. This grouping is mapped to/from a file system data structure associated with a traditional block appended checksum disk drive.Type: GrantFiled: May 21, 2002Date of Patent: December 13, 2005Assignee: Network Appliance, Inc.Inventors: Anthony F. Aiello, John Lloyd, Kyquang Son
