Patent number: 5905695Abstract: Recording of information is performed by selectively forming a high-temperature level state and a low-temperature level state on a recording medium which is capable of an optical modulation overwrite operation to multi-value power levels on the basis of a multi-pulse recording waveform. A power level PHth of the light beam immediately before the high-temperature level state begins to be formed on the medium is detected and a minimum power level PLmin of the light beam, which can form the low-temperature level state on the medium, is detected. Then, the multi-pulse recording waveform is switched on the basis of the detected power levels PHth and PLmin. Upon recording of a non-overwrite recording medium, a power level Pth of the light beam immediately before recording begins on the medium is detected and a maximum reproduction power level Prmax of the light beam at which information recorded on the medium is not erased is detected.Type: GrantFiled: August 28, 1996Date of Patent: May 18, 1999Assignee: Canon Kabushiki KaishaInventor: Shunpei Kimura

Patent number: 5815477Abstract: A write test method for use in a recording process for recording information is effected by such that the power of a laser light is modulated to form a high-temperature state and a low-temperature state on a recording medium. First, a predetermined signal is recorded on the recording medium while varying the power level of the laser light. The information recorded on the recording medium is reproduced to detect the power level of the laser light, immediately before formation of the high-temperature state, based on the amplitude of a reproduced signal. The power levels of the laser light for forming the low-temperature state and for forming the high-temperature state are determined on the basis of the detected power level.Type: GrantFiled: January 30, 1996Date of Patent: September 29, 1998Assignee: Canon Kabushiki KaishaInventors: Shunpei Kimura, Takaaki Ashinuma, Tsutomu Shiratori, Akira Miyashita
