Patent number: 7349623Abstract: According to the invention, techniques for recording data onto recording media at relatively high transfer rates for relatively long periods of time. Embodiments according to the present invention include systems and apparatus capable of an improved sustained rate of data recording onto disk type-recording media, for example. Many embodiments can remove the upper limits of both recording capacity and the number of media that can be used. Select embodiments can be used with different kinds of recording media as well. In a specific embodiment, the area on a hard disk is divided into three areas. A first area can be suitable for sequential recording of continuous data. A second area can be suitable for random recording of discontinuous data. A third area can be used for recording logical sector numbers, coupling logical sector numbers, and file information that are used for marking each of the first and second areas, so that continuous data can be recorded on the hard disk at a high data rate.Type: GrantFiled: March 17, 2000Date of Patent: March 25, 2008Assignee: Hitachi, Ltd.Inventors: Kouji Fujita, Hideo Nishijima, Kazuya Yamashita

Publication number: 20070058509Abstract: In a conventional method for preventing a collision between a lens and an optical disc which uses a control system similar to the servo control of the optical disc, it is feared that, when there is no need to apply the servo, the collision prevention method may not perform its function satisfactorily. In an optical disc device that operates with a part of its functions suspended for reduced power consumption, the conventional method is not enough to avoid the collision between the lens and the optical disc. By arranging the lens/disc collision prevention mechanism independently operable, it is possible to prevent the collision between the lens and the disc even during the operation with limited functions.Type: ApplicationFiled: July 25, 2006Publication date: March 15, 2007Applicant: Hitachi, Ltd.Inventors: Takahiro Matsuda, Kouji Fujita

Patent number: 6987924Abstract: A recorder/reproducer for recording and reproducing signals such as video and audio signals has first and second recording media. When an input signal is recorded on the first recording medium, it is once recorded on the second recording medium, and a certain time later it is transferred to the first recording medium, thus recorded thereon. During this certain time, other signal processings are made, such as recording/reproduction of other signals and discrimination of commercials from the program itself. In addition, when a signal is reproduced from the first recording medium, the signal is once recorded on the second recording medium, and a certain time later reproduced and supplied, and thus similarly other processings can be made during this certain time.Type: GrantFiled: April 23, 1999Date of Patent: January 17, 2006Assignee: Hitachi, Ltd.Inventors: Kouji Fujita, Hideo Nishijima, Motoyoshi Sasaki

Publication number: 20050276180Abstract: There are cases where image contents with a limited number of copies allow data transfer although not dubbing operations. Transfer of temporarily recorded data from a recording medium such as a hard disk to a recording medium such a DVD-R raises a problem of erasing hard disk data for transfer even in case of incomplete data transfer. The disclosure of the present invention therefore describes determination means for determining a result of data transfer based on a condition for the transfer of the above-mentioned data allows a failure in data transfer to be prevented. This eliminates a concern over erasing HDD data for transfer during an incomplete data transfer.Type: ApplicationFiled: February 14, 2005Publication date: December 15, 2005Applicant: Hitachi, Ltd.Inventors: Kouji Fujita, Hiroaki Ono

Patent number: 5808824Abstract: A capstanless tape feed control system of a reel-drive type is capable of accurately detecting the respective working radii of a supply reel and a take-up reel and the total length of the tape, of efficiently controlling tape speed and of preventing damage to the tape. The tape feed control system calculates the working radii of the supply reel and the take-up reel and the total length of the tape while the leading end of the tape is moving toward the take-up reel, and detects tape speed on the basis of data representing the total length of the tape and the radius ratio between the supply reel and the take-up reel. The tension of the tape and the reel driving torque are detected while the tape is being fed and the working radii of the supply reel and the take-up reel are calculated on the basis of the tension and the reel driving torque.Type: GrantFiled: December 6, 1995Date of Patent: September 15, 1998Assignee: Hitachi, Ltd.Inventors: Kouji Kaniwa, Kouji Fujita, Shigemitsu Higuchi, Nobuyuki Kaku
