Patent application numberDescriptionPublished
20090116354Recording parameter setting device, program thereof, computer-readable recording medium containing the program, information recording medium, recording/reproducing device, and recording parameter setting method - A recording parameter setting device including a trial recording parameter setting section and a reproduced signal quality judging section. The reproduced signal quality judging section judges whether or not a reproduced signal obtained by reproduction of the trial recording carried out in accordance with the trial recording parameter satisfies a predetermined reproduced signal quality. If no, the recording parameters of the predetermined recording mark length or longer are further classified into detailed groups and trial recording is carried out again. If the reproduced signal satisfies the predetermined reproduced signal quality, the reproduced signal quality judging section sets the trial recording parameters as a recording parameter. This makes it possible to form a recording mark capable of surely providing a good reproduced signal quality while the number of recording parameters to be used is reduced.05-07-2009
20100188948Recording parameter setting device, program thereof, computer-readable recording medium containing the program, information recording medium, recording/reproducing device, and recording parameter setting method - A recording parameter setting device includes a trial recording parameter setting section (07-29-2010
20100188949Recording parameter setting device, program thereof, computer-readable recording medium containing the program, information recording medium, recording/reproducing device, and recording parameter setting method - A recording parameter setting device includes a trial recording parameter setting section (07-29-2010
20100188954Recording parameter setting device, program thereof, computer-readable recording medium containing the program, information recording medium, recording/reproducing device, and recording parameter setting method - A recording parameter setting device includes a trial recording parameter setting section (07-29-2010
20100188955Recording parameter setting device, program thereof, computer-readable recording medium containing the program, information recording medium, recording/reproducing device, and recording parameter setting method - A recording parameter setting device includes a trial recording parameter setting section (07-29-2010
20100188956Recording parameter setting device, program thereof, computer-readable recording medium containing the program, information recording medium, recording/reproducing device, and recording parameter setting method - A recording parameter setting device includes a trial recording parameter setting section (07-29-2010
20100188958Recording parameter setting device, program thereof, computer-readable recording medium containing the program, information recording medium, recording/reproducing device, and recording parameter setting method - A recording parameter setting device includes a trial recording parameter setting section (07-29-2010

Patent application numberDescriptionPublished
20100165808INFORMATION STORAGE MEDIUM, INFORMATION READ/WRITE DEVICE, COORDINATION SYSTEM, CONTROL PROGRAM FOR THE DEVICE OR SYSTEM, AND COMPUTER-READABLE STORAGE MEDIUM - There are provided at least a first information storage area 07-01-2010

Atsushi Etoh, Tenri-Shi Nara JP

Patent application numberDescriptionPublished
20090073835Recording Parameter Setting Device, Program Thereof, Computer-Readable Recording Medium Containing the Program, Information Recording Medium, Recording/Reproducing Device, and Recording Parameter Setting Method - A recording parameter setting device includes a trial recording parameter setting section (03-19-2009
20100067346Recording mark formation method, information recording device, information recording method, and information recording medium - In an information recording/reproducing device, a resting period (tm) is set to be constant regardless of a mark length of a recording mark and regardless of the number of divided recording pulses. Consequently, it is possible to provide an information recording device, an information recording method, and an information recording medium, each allowing formation of a recording mark with a uniform width by use of a low laser power and allowing reduction of the number of parameters for determining a recording waveform, when forming a long recording mark.03-18-2010
