Patent number: 7019931Abstract: The present invention provides a tape drive apparatus enabled to directly and accurately detect dew condensation on a rotary head drum. Tape serving as a recording medium is drawn out of a cartridge. The drawn tape runs in such a way as to be wound on a tape takeup reel provided in a tape drive apparatus body. Signals are recorded on and reproduced from the tape by winding the drawn tape around the rotary head drum. This tape drive apparatus has a prethreading mechanism that brings the tape into slight contact with the rotary head drum before the tape is completely wound therearound. Dew condensation on the rotary head drum is detected by rotating the rotary head drum during a status in which the tape is brought by the prethreading mechanism into contact with the rotary head drum.Type: GrantFiled: December 3, 2003Date of Patent: March 28, 2006Assignee: Sony CorporationInventors: Yasuaki Kano, Atsushi Mitani, Masaki Yoshizawa, Toshiya Kurokawa

Patent number: 6930854Abstract: A tape library wherein a number of cassette tapes are accommodated and adjusted. One or more expansion units are connected to a basic unit. When a transport mechanism is within the basic unit, a control circuit section controls the transport mechanism by referencing a position reference point of the basic unit, and when the transport mechanism is within an expansion unit the control circuit section controls referencing a position reference point of the expansion unit. The control circuit section and the transport mechanism of the basic unit are interconnected by an elongated-belt-like flat cable which includes a plurality of conductors extending in parallel and joined with an insulating material, and when an expansion unit is coupled the cable need not be replaced, allowing coupling of an expansion unit and smooth transportation of a recording medium in the expansion unit to a recording and/or playback section by the transport mechanism.Type: GrantFiled: November 5, 2001Date of Patent: August 16, 2005Assignee: Sony CorporationInventors: Yoshitsugu Taki, Masahiro Kodama, Ryuji Takatsuka, Toshiya Kurokawa

Patent number: 6865047Abstract: A single-reel tape cartridge includes a leader block and a take-up reel disposed inside a drive apparatus that are provided with retaining members so that the leader block is firmly positioned and rattling thereof is prevented. A pair of changer grips which extend from end to end of a housing of the cartridge in the vertical direction are formed at two corners of the cartridge housing. In addition, a memory module, which stores the management information for the tape-like recording medium and which is used for radio communication, is disposed at an angle in one of the corners of the cartridge so that a communication antenna of the memory module faces at least two directions. In addition, the leader tape is provided with a striped portion used for identifying the medium, and the cartridge housing is closed by a shutter used for disengaging the reel lock.Type: GrantFiled: November 2, 2001Date of Patent: March 8, 2005Assignee: Sony CorporationInventors: Katsumi Maekawa, Toshiya Kurokawa, Yasuaki Kano, Atsushi Mitani, Yoshitsugu Taki, Motoyoshi Fujimori

Patent number: 6829117Abstract: An antenna is provided for use with a memory (MIC) incorporated in a recording medium that stores management data. The antenna is located at a position to read data signals from the memory before the recording medium inserted through an insertion port is completely transported to the transport mechanism of a drive. Thus, a recording/playback apparatus and a data library can be provided, which can use a large amount of information to manage the recording medium as management data before the recording medium is inserted into the drive.Type: GrantFiled: June 24, 2002Date of Patent: December 7, 2004Assignee: Sony CorporationInventors: Yoshitsugu Taki, Masahiro Kodama, Toshiya Kurokawa

Patent number: 6762903Abstract: A tape drive uses a single-reel type tape cassette, and includes a pull-back guide shaft for pulling back a tape-shaped recording medium at a predetermined position and a pair of moveable guide pins, whereby the tape-shaped recording medium is positioned between the paired guide pins is wound around the drum. A tension device applies a predetermined tension when the tape-shaped recording medium has been drawn out and a tape path has been formed. A non-winding fast feed mode is set in which the tape-shaped recording medium is fed at high speed under a predetermined tension wherein the tape-shaped recording medium is not wound around the drum. The tension device has a tension regulator lever having two guide shafts for both winding feed mode and non-winding feed mode.Type: GrantFiled: January 29, 2002Date of Patent: July 13, 2004Assignee: Sony CorporationInventors: Yasuaki Kano, Toshiya Kurokawa, Katsumi Maekawa, Atsushi Mitani
