Patent number: 8897113Abstract: A data storage and retrieval system includes a head carriage unit adapted for rotational motion and having multiple heads disposed at a working surface. The system also includes a tape drive unit configured to move a tape media past the working surface of the head carriage unit, the tape media having a width approximately equal to a width of the working surface. As the head carriage unit rotates and the tape moves past the working surface, a first head is configured to write a data track to the tape and a second head is configured to thereafter read the data track, where data read by the second head is for use in verifying data integrity and performing error correction.Type: GrantFiled: November 7, 2012Date of Patent: November 25, 2014Assignee: Oracle International CorporationInventors: Carl Madison, Timothy C.

Patent number: 8035972Abstract: A cooling system for cooling computer component with a liquid provided at atmospheric pressure, or low pressure, that flows through channel defined in the computer component. The liquid is pumped from a reservoir to a discharge port, or weir, that is located above the computer component. The liquid flows through an in-feed manifold to diverters that direct the liquid into in-feed tanks located above a row of the computer component. The liquid flows through the channels and flow control orifices to a drain that returns the liquid to the reservoir.Type: GrantFiled: July 31, 2009Date of Patent: October 11, 2011Assignee: Oracle America, Inc.Inventors: Timothy C.

Patent number: 7273344Abstract: A data storage library and method of operation are disclosed wherein access at least to part of at least one robotics mechanism from the data storage library's exterior is permitted. Access is accomplished through a service port in the library's housing. Access to the storage cells, and thus the data cartridges sitting therein, from the library's exterior is blocked. Blocking access to the storage cells may be provided by a geometry of the service port itself, or by a combination of a door and the robotics mechanism being serviced filling the opening created by the service port. For robotics mechanisms operating on a track, part of the track may be routed through the service port to bring the robotics mechanisms to the exterior of the library for maintenance purposes.Type: GrantFiled: November 13, 2003Date of Patent: September 25, 2007Assignee: Storage Technology CorporationInventors: Timothy C. Ostwald, Daniel James Plutt

Patent number: 7255525Abstract: A safety system for online servicing of a media library is provided, wherein the library comprises a plurality of media storage cells and at least one media picker robot that moves along the media storage cells, and wherein the library is contained within an enclosure having at least one access means. The safety system detects whether the access means in the enclosure is open or closed and operates the robot in the media library in one of two corresponding modes. If the access means is closed, the robot operates in a normal mode at a first specified speed. If the access means is open, the robot operates in a safe mode at a second specified speed that is slower than the first speed of the normal mode. In another embodiment, while in safe mode, the picker robot is excluded from moving within a restricted zone in the library.Type: GrantFiled: December 19, 2001Date of Patent: August 14, 2007Assignee: Storage Technology CorporationInventors: Frank Tucker Smith, Timothy C. Ostwald, James M. Frary
