Patent number: 10642533Abstract: A configuration for reducing a possibility of data recording or reproduction being unperformable due to a reading error of disc management information is realized. A data processing unit records management information corresponding to a first surface as main management information on the first surface which is a data recording surface on which data recording is performed and further records mirror management information having the same content as the main management information on a second surface different from the first surface. The management information is, for example, a temporary disc management structure (TDMS) including defect region information of one surface of a disc. When one piece of management information between the main management information and the mirror management information is successfully read, data recording or reproduction can be correctly performed.Type: GrantFiled: March 2, 2016Date of Patent: May 5, 2020Assignee: SONY CORPORATIONInventors: Motohiro Terao, Takashi Nagatomo, Hideki Ando

Patent number: 9997188Abstract: A configuration for preventing a recording error when a data recording process is performed on both lands and grooves of an optical disc is realized. An information processing device includes a data processing unit configured to control a data recording process on both lands and grooves of an optical disc. The data processing unit performs a process of detecting or matching positions at which data recording states of grooves or lands on both sides adjacent to a data recording target land or groove match when data are recorded on the lands or the grooves. The data processing unit performs, for example, a dummy data recording process or a skipping process as the process of matching the data recording states of the grooves or the lands on both sides adjacent to the data recording target land or groove.Type: GrantFiled: March 2, 2016Date of Patent: June 12, 2018Assignee: SONY CORPORATIONInventors: Motohiro Terao, Takashi Nagatomo

Patent number: 7916593Abstract: An optical disk device capable of increasing access speed and an image pickup device having such an optical disk device. In a region at the inside of an optical disk where the rotational speed of the spindle motor reaches its limit, a CAV mode is used for access, while in a region at the outside of the optical disk where a frequency band of an RF signal processor reaches its limit, a CLV mode is used for access. High-speed access to a maximum extent in a range of performance limits of the spindle motor and the RF signal processor is achieved. A retry feature retries failed access attempts to the optical disk when access failure is determined and a controller judges whether or not a defect of the optical disk has caused the access failure. The controller further judges if the predetermined cause of the access failure repeatedly occurs in a predetermined nearby range on the optical disk.Type: GrantFiled: February 23, 2005Date of Patent: March 29, 2011Assignee: Sony CorporationInventors: Norio Tanaka, Takashi Nagatomo, Akio Terada, Yuichi Suzuki
