Patent number: 7945419Abstract: In a method of electronically measuring reel off-center run-out and reel hub mismatch, tape speed data related to a tape coupled with an operating drive reel is electronically measured. The tape speed data is correlated with drive reel rotation angles. The correlated tape speed data is translated to drive reel hub radii variations with respect to the drive reel rotation angles. The drive reel hub radii variations comprise an operational measure of reel off-center run-out and reel hub mismatch of the drive reel.Type: GrantFiled: August 14, 2008Date of Patent: May 17, 2011Assignee: Quantum CorporationInventors: Ming-chih Weng, Turguy Goker, James Mark Decot, Minh Vu, John A.

Patent number: 7455254Abstract: A method and apparatus for preventing the detachment of an end of tape from a hub filler during movement of the hub filler along a guide rail during an unloading operation of a tape drive mechanism. Detachment is prevented by a retracting tape dragging the hub filler along the guide rail, so as to maintain adequate tension that prevents detachment of the tape from the hub filler. The hub filler, which is coupled to the tape, guide arm, and guide rail, provides adequate drag force to maintain tension in the tape and prevent damage to the tape or the tape drive mechanism.Type: GrantFiled: July 25, 2001Date of Patent: November 25, 2008Assignee: Certance LLCInventors: Turguy Goker, John A. Hamming, Russell A. Bauer, Kempton W. Redhead

Patent number: 7338002Abstract: A dual hub reel for a tape drive comprises an inner hub operatively connectable to a motor and a flexible leader connected at a first to the inner hub so as to be wound on to the inner hub when driven, to rotate by the motor. An outer hub is disposed about the inner hub and has an opening through which the flexible leader extends. The outer hub is arranged on the inner hub and is selectively freely rotatable about the inner hub or locked against the inner hub to rotate with the inner hub. A locking element is responsive to pressure supplied by a tape wrap to press against the inner hub and lock the outer hub to the inner hub by interaction of an engagement surface against the inner hub.Type: GrantFiled: October 18, 2006Date of Patent: March 4, 2008Assignee: Quantum CorporationInventor: John A.

Patent number: 7066420Abstract: A tape drive apparatus with an arrangement for capturing, retaining and releasing a leader pin from the tape cartridge provides a leader pin holding assembly having a body and a swing pivotally coupled to the body. Upon movement into the tape cartridge, the swing is controllably pivoted against the force of a spring into an open position to capture the leader pin within the tape cartridge. Closing the swing retains the leader pin between the swing and the body of the leader pin holding assembly. A minimum number of external actuators is achieved by employing a hub leader that controls the opening and closing of the swing with relation to the body.Type: GrantFiled: December 19, 2003Date of Patent: June 27, 2006Assignee: Certance LLCInventor: John A. Hamming

Patent number: 6744593Abstract: A tape drive having a cartridge receiving area for receiving a cartridge containing a recording medium on a supply reel is disclosed. The tape drive has a take-up reel. The take-up reel includes a take-up rotatably mounted to the tape drive and a pair of flanges mounted on either side of the take-up hub. A magnetic read/write head is disposed between the cartridge receiving area and the take-up reel. A pair of fixed guide assemblies is disposed symmetrically about the magnetic read/write head. Each of the fixed guide assemblies has a fixed guide mount fixed to the tape drive, a fixed guide attached to a top of the fixed guide mount, and a spring/pressure pad having at least one pressure pad mounted to the fixed guide, wherein the pressure pad applies pressure to a top edge of the recording medium when the tape drive is operational. The tape drive also has a forward guide roller and a rearward guide roller disposed symmetrically about the magnetic read/write head.Type: GrantFiled: October 13, 2000Date of Patent: June 1, 2004Assignee: Seagate Technology LLC.Inventors: Ashok B.

Patent number: 6619577Abstract: A method of loading a tape from a single reel tape cartridge into a take-up reel. Position sensors detect position of a guide arm as a tape loading mechanism loads and unloads tapes from a single reel tape cartridge. The position sensors are accurate and eliminate problems that occur from small misalignments of hub filler access with the access of the take-up reel. Further, the position sensors enable the hub filler to consistently attach to a leader pin at the end of the tape of the single reel tape cartridge without frequent malfunctions.Type: GrantFiled: April 23, 2001Date of Patent: September 16, 2003Assignee: Seagate Removable Storage Solutions LLCInventors: John A.
