Patent number: 7760601Abstract: Conventional reproducing apparatuses used to perform incorrect detection or consume electricity considerably. According to the present invention, the comparator 61 comparing voltages at both ends of the spindle motor 15 and outputting the result is provided, and the control IC 12 judges whether or not the spindle motor 15 is rotating based on the output from the comparator 61. Based on this judgment, brake pulses are repeatedly supplied to the spindle motor 15 until the spindle motor 15 stops. Based on the number of times the brake pulses are supplied until the spindle motor 15 stops, the presence or absence of an optical disk in the disk drive is determined.Type: GrantFiled: November 5, 2007Date of Patent: July 20, 2010Assignee: Funai Electric Co., Ltd.Inventor: Yasumasa Igi

Patent number: 7548492Abstract: The optical disk recording/reproduction device is provided with an information recording area search means, comprising, a moving means which detects the presence and absence of information and return moves an optical pickup from inward to outward or from outward to inward direction of an optical disk, and a stopping means which stops the movement of optical pickup if an information recording area is detected in the movement of optical pickup. If the existence of information cannot be confirmed at a re-zeroing position in the initial operation, the optical pickup is moved to the inward of optical disk at a normal velocity; when the optical pickup passes through the information recording area, it is braked and stopped. If the existence of information can be confirmed at the stop position, the flow is shifted to normal reproduction; if it cannot be confirmed, the optical pickup is determined to pass through the information recording area and stop, returned from the stop position and moved outward at a low speed.Type: GrantFiled: September 2, 2005Date of Patent: June 16, 2009Assignee: Funai Electric Co., Ltd.Inventor: Yasumasa Igi

Patent number: 7457211Abstract: An optical apparatus calculates, based on the information data recording time, a recording area recording information data and an area to be finalized that is expected to become an unrecorded area after the information data is recorded, and alternately repeats recording of information data into the recording area and finalization including recording of predetermined dummy data into an area to be finalized a predetermined distance away from the calculated information data recording area. Once recording of the information data is complete and the information data recording area is fixed, the apparatus records predetermined dummy data into a remaining non-finalized area of the recording medium to perform finalization.Type: GrantFiled: September 20, 2005Date of Patent: November 25, 2008Assignee: Funai Electric Co., Ltd.Inventor: Yasumasa Igi

Publication number: 20060077881Abstract: An optical recording medium comprises a base layer, recording layers formed on the base layer so that pits, which cause light reflection different from that of areas around the pits, are formed thereon, encoded data pits formed on each of the recording layers in an arrangement corresponding to encoded data produced by encoding information, and visual information-display pits formed on each of the recording layers to have a width larger than that of other pits so as to display visible information. The recording layers are stacked on one side of the base layer. The visual information-display pits are formed in corresponding areas on the respective recording layers. This configuration can produce clearer transitions between light and dark on the optical disc so that the visible information can be displayed to be easily viewable as compared with a conventional configuration where visual information-display pits are formed on only a single recording layer.Type: ApplicationFiled: September 15, 2005Publication date: April 13, 2006Applicant: Funai Electric Co., Ltd.Inventors: Yasumasa Igi, Hironori Tani

Publication number: 20060077818Abstract: A controller in an optical disc processor serves as a visual information recording unit for recording visible information by forming visual information-display pits to be closely aggregated together in a given display pattern, the visual information-display pits having a width larger than that of other pits, wherein the title information is contained in a TOC to be recorded on an optical disc. The visual information-display pits are formed on a recording layer closest to a base layer and different from a recording layer on which to form encoded data pits. This makes it possible to record visible information on the optical disc without requiring a user to separately input data for visual information recording.Type: ApplicationFiled: September 14, 2005Publication date: April 13, 2006Applicant: Funai Electric Co., Ltd.Inventors: Masanori Ujino, Yasumasa Igi
