Publication number: 20080144469Abstract: A BCA signal reproduction method for reading a BCA signal from a disc includes detecting a peak value of the BCA signal (peak detection value); detecting a bottom value of the BCA signal using a wide tracking bandwidth (first bottom detection value); detecting a bottom value of the BCA signal using a narrow tracking bandwidth (second bottom detection value); detecting a signal indicating whether the current portion is a no-signal portion where the BCA signal is not recorded or a signal portion where the BCA signal is recorded, on the basis of the peak detection value, the first bottom detection value, and the second bottom detection value; determining a slice level for binarizing the BCA signal on the basis of the detected signal and at least the peak detection value, the first bottom detection value, and the second bottom detection value; and binarizing the BCA signal.Type: ApplicationFiled: December 7, 2007Publication date: June 19, 2008Applicant: Kabushiki Kaisha ToshibaInventors: Hiroaki Morino, Yukiyasu Tatsuzawa, You Yoshioka

Publication number: 20080144471Abstract: A disk image is generated, stored in at least one persistent storage device, comprises at least one software application, and is a root disk image. An inheritance tree comprising a root node associated with the root disk image is created. A new disk image of a disk is generated based on a previously generated disk image associated with a node of the inheritance tree. The new disk image is stored in at least one persistent storage device, and comprises at least one software application of the previously generated disk image and at least one new software application. The new disk image shares at least one data block of the previously generated disk image. A new node is added to the inheritance tree, and is associated with the new disk image. The new node is a child node of the node that is associated with the previously generated disk image.Type: ApplicationFiled: December 18, 2006Publication date: June 19, 2008Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Rekha Devi Garapati, Zhe Xiang, Velnambi Yogalingam, Kai Gee Hoong Young

Publication number: 20080144473Abstract: An optical element is for generating recording signal light and reference light interferes with the recording signal light by changing an orientation state of a liquid crystal to record optical information on a recording medium through volumetric recording. The optical element includes a first polarizing element; a second polarizing element; and a liquid crystal layer that is arranged between the first polarizing layer and the second polarizing layer. An extinction angle of less than 90 degrees is formed by a light transmission axis of the first polarizing element and a light transmission axis of the second polarizing element.Type: ApplicationFiled: January 24, 2008Publication date: June 19, 2008Applicant: FUJITSU LIMITEDInventor: Yasuaki Morimoto

Publication number: 20080144474Abstract: An information recording and/or reproducing apparatus capable of obtaining a certain recording/reproducing margin with a simplified structure. The apparatus identifies whether an optical disc is a single-layer recording medium having one recording layer or a multilayer recording medium having a plurality of recording layers, and sets a control range (movable range) of an object lens on the basis of the identification result. When the optical disc is identified as a multilayer recording medium, the control range of the object lens is set to be smaller than that for a single-layer recording medium. Further, the control range of the object lens is set for each of the recording layers of the optical disc.Type: ApplicationFiled: November 29, 2007Publication date: June 19, 2008Applicant: CANON KABUSHIKI KAISHAInventor: Toshihiko Suzuki

Publication number: 20080144477Abstract: Methods and apparatus are provided for recording/reproduction of data in a probe-based data storage device (1) in which application of a write signal causes formation of an indentation in a storage surface (5) by a probe of the device (1). Instead of storing information in the presence or absence of indentations on the storage surface as is conventionally done in such devices, information is stored in the form of grooves of variable length separated by lands of variable length. More particularly, a sequence of n>1 successive bits of a first value (typically “1's”) in a recording signal is recorded by applying a series of write signals at respective probe-positions on the storage surface (5). These probe-positions are spaced at w?M, where M is the indentation merging distance, so that the resulting indentations merge to form a groove in the storage surface (5) spanning n readback sample positions.Type: ApplicationFiled: November 23, 2007Publication date: June 19, 2008Applicant: International Business Machines CorporationInventors: Evangelos S.
