Patent number: 7729217Abstract: The present invention aims to smoothly and adequately adjust recording laser power while an increase in processing load during recording is suppressed. When a recording operation start request is received, OPC is executed with reference to a target ? value (?t) of a disc to set recording laser power Pws. Recording operation is performed based on the set recording laser power Pws. When a system is brought into an intermittent standby state, R-OPC is executed, so the recording laser power Pws is adjusted and set again. Then, its subsequent recording operation is performed based on the recording laser power Pws which is set again. When a duration of the recording operation exceeds a maximal waiting time Ts, the recording operation is suspended so that the system is set to a recording standby state. Then, the R-OPC is executed, so that the recording laser power Pws is adjusted and set again.Type: GrantFiled: March 11, 2005Date of Patent: June 1, 2010Assignee: Sanyo Electric Co., Ltd.Inventors: Ken Hirose, Noboru Mamiya, Kenji Nakao, Satoshi Sumi, Koichi Kawakami
