Abstract: PROBLEM TO BE SOLVED: To enable grasping quickly a format situation of a whole disk in an optical disk recording medium in which data can be rewritten and which has a recording layer being multi-layers. SOLUTION: A formatting bit map managing parts of format/unformatted in a whole recording layer is recorded for one recording layer. Movement between layers can be made unnecessary when a format situation of the whole disk is grasped, thereby, grasping the format situation of the whole disk can be performed quickly.

Abstract: PROBLEM TO BE SOLVED: To shorten a formatting time required at the time of discharging a disk in an optical disk recording medium in which data can be rewritten and which has a recording layer being multi-layers. SOLUTION: In this recording method, background format is performed preferentially from a recording layer in which recording of user data is to be performed last out of a plurality of recording layers. For example, when interchangeability with a reproduction exclusive apparatus is requested at the point of time at which recording of the user is performed in only a first recording layer, it is required that format (recording of dummy data) is performed in all recording layers in an unrecorded region of an inner periphery side more than a terminal position of the user data in the first recording layer, a part in which format is to be performed in a recording layer in which recording is to be performed last can be decreased at the time of discharging the disk by performing background format preferentially from the recording layer in which recording is to be performed last.

Abstract: PROBLEM TO BE SOLVED: To shorten the recording time in a recordable multilayer disk and to improve the reliability as to a recording medium including a plurality of information recording layers and a recording device and a recording method to cope with the recording medium. SOLUTION: On the basis of the total amount of data recorded in the recording medium of a multilayer structure, an area range is set for performing data writing making each of recording layers as a target. Especially, the setting is made to minimize the recording amount of a tail end area (readout) formed for reproduction compatibility, and then a recording operation time is shortened. During reproduction, on the basis of the total amount of data to be recorded from the place of a high possibility of accurate information reproduction, an area range for performing data writing is set making each of the recording layers as the target. Thus, a highly reliable data writing operation is realized. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To reduce seek operation to an exchange area in the case of reading data. SOLUTION: It is discriminated whether or not a boaded disk has been subjected to exchange processing (S001 and S002). When the disk is discriminated to have been subjected to exchange processing, it is discriminated whether or not an instruction (e.g. recording, reproduction, etc.), from a host computer is carried out (S003), and when the instruction is discriminated not to be carried out, an exchange sector is accessed, and exchange data are reproduced and stored in a cache memory (S004 and S005).

Abstract: PROBLEM TO BE SOLVED: To restrict the reproduction of data recorded on a disk. SOLUTION: An extension RID code composed of information, etc., for restricting copyright information and the number of reproducing times is recorded on run-in blocks and run-out blocks forming a packet. Reproduction restriction information is also recorded as the attribute information of contents. In a reproduction mode, the approval/denial of data reproduction is discriminated on the basis of the reproduction restriction information recorded together with the data and reproduction is carried out on the basis of the discrimination results.

Abstract: PROBLEM TO BE SOLVED: To efficiently read data recognizing a defective packet. SOLUTION: When packet write processing is started (S001), data are recorded in packet units (S002-S008), and when it is discriminated that retrials have been done the prescribed number of times, alternate processing is executed (S012). Then, for example, defect discriminating information is recorded in the alternated packet, and alternation discrimination information is recorded in the alternating packet (S013). In such a manner, it is possible to let the disk drive discriminate the defective packet at the time of reproduction. Therefore, when data recorded in a disk in which the defective discrimination information is recorded are reproduced, it is possible to prevent the data in the defective packet from being stored in buffer memory based on the fact that the defective discrimination information is detected.

Abstract: PROBLEM TO BE SOLVED: To handle data of a memory card equivalently to data of a hard disk device in a host computer. SOLUTION: When a recording and reproducing device makes transition to a state that communication with the memory card is possible, whether or not an MBR is requested from the host computer based on, for example, an address, etc., is discriminated (S110), when the MBR is discriminated to be requested, data of the MBR is processed (S111). Furthermore, whether or not a PBR is requested from the host computer is discriminated (S112), and when the PBR is discriminated to be requested, data of the PBR is processed (S113). The requested data are transferred to the host computer (S114). In addition, when the data is recorded in the memory card, when the MBR and the PBR are transferred from the host computer, pieces of the data are also processed and pieces of the processed data are recorded in the memory card.

Abstract: PROBLEM TO BE SOLVED: To reduce a formatting time. SOLUTION: Null data 84 are recorded only in a portion of a program region rather than recording the Null data in the entire region. Then, user data 87 are recorded in a nonrecorded region 85 where no data such as the data 84 are recorded. The data 87 are randomly recorded in the region 85. Thus, reproducing interchangeability is made possible with a reproducing dedicated device.

Abstract: PROBLEM TO BE SOLVED: To extend an expression range of a track number and an index number of a sub-code keeping interchangeability for a standard disk. SOLUTION: A value which can be expressed as a track number in a range of 8 bits being same as a conventional sub-code format, a track number indicated by point information, and an index number is extended by using a binary code of 8 bits in track number information of a sub-code, point information, and index information index information. Also, conflict of a setting value of conventional specific definition as a track number and point is prevented by restricting a value corresponding to a track number itself or an index number itself to a range of '01'-'9F' in a binary code, thereby, interchangeability is kept suitable.

Abstract: PROBLEM TO BE SOLVED: To easily judge whether or not an optical disk is the disk whose recording capacitance has been made large. SOLUTION: The synchronizing pattern of ATIP information to be buried into the guide groove of a light spot is made to be the different synchronizing pattern in a high density optical disk, for example, '3T+3T+1T+1T' ('T' is the minimum channel bit of a signal which is obtained by reading position information) with respect to the synchronizing pattern of a standard density optical disk, which is '3T+1T+1T+3T', whose recording capacitance has not been made large. ATIP information is read and the synchronizing pattern is judged so that it can be easily and rapidly judged whether the optical disk is the standard density one or the high density one.
