Patent number: 5978185Abstract: Disclosed in an arrangement to achieve satisfactory head contact by increasing contact face pressure at a head gap and to reduce the change in time of head contact performance in a double azimuth head. Heads in a portion in which a tape is slid are respectively constructed with each head having two different arcs with a radius of curvature R1 in a first area which includes a gap, and with a radius of curvature R2 in a second area which is adjacent to the first area. A transition portion P for transitioning an arc with the radius of curvature R1 and an arc with the radius of curvature R2 is located in the direction of its adjacent head based upon a contact point Q on R1 of a common tangent drawn from an arc forming a periphery of a rotating drum to a circle formed by R1. The relationship between the radiuses of curvature in two areas is set to R1>R2.Type: GrantFiled: December 23, 1996Date of Patent: November 2, 1999Assignee: Hitachi Ltd.Inventors: Fukuyasu Abe, Kenmei Masuda, Shinya Fujimori, Hidekazu Takeda, Atsushi Inoue, Yoshiharu Yamashita, Kuniaki Hirayama, Yoshio Uemura, Masahiko Fujishiro, Toshihiko Imachi

Patent number: 5608585Abstract: A tape run control unit in the magnetic recording/reproducing apparatus is provided with a discrimination element and a control element. The discrimination element detects a stand-by time until a signal to be recorded is received in repositioning of the tape and generates a discrimination signal for discriminating the length of the stand-by time. The control element controls tape run driving unit such as a capstan motor during the reposition and controls the stop position of the tape such that a magnetic head scans the portion of the tape where no data is recorded. After completion of repositioning, furthermore, the control element works according to a discrimination signal so as to select the stop mode which involves the release of pinch roller when the stand-by time is long and to select the mode for simply stopping only the capstan when the stand-by time is short.Type: GrantFiled: June 5, 1995Date of Patent: March 4, 1997Assignee: Hitachi, Ltd.Inventors: Kenmei Masuda, Kenji Ogiro, Hidefumi Goto, Sadao Hirose, Satoshi Fujino, Shinya Fujimori, Katsuhiko Izumi

Patent number: 5448427Abstract: A tape run control unit in a magnetic recording and reproducing apparatus is provided with a discriminator and on a controller. The discriminator detects a stand-by time until a signal to be recorded is received in repositioning of the tape and generates a discrimination signal for discriminating the length of the stand-by time. The controller controls tape driving unit such as a capstan motor during the reposition and controls the stop position of the tape such that a magnetic head scans the portion of the tape where no data is recorded. After completion of repositioning, furthermore, the controller is responsive to a discrimination signal so as to select the stop mode which involves the release of pinch roller when the stand-by time is long and to select the mode for simply stopping only the capstan when the stand-by time is short.Type: GrantFiled: August 2, 1990Date of Patent: September 5, 1995Assignee: Hitachi, Ltd.Inventors: Kenmei Masuda, Kenji Ogiro, Hidefumi Goto, Sadao Hirose, Satoshi Fujino, Shinya Fujimori, Katsuhiko Izumi
