Abstract: SO1891 In a system for recording and reproducing digital signals on a magnetic tape using a rotary head, in which the signals are recorded as a series of slanted tracks without guard bands between adjacent slanted tracks, a pilot signal that was recorded during the recording process is used to control the tracking of the playback head. The pilot signal is recorded at a specific position in a specific pilot signal record region, independent from the region of the track at which the informational signal is recorded and the pilot signal is arranged at a predetermined position or positions being a specified distance from an end of each track in its longitudinal direction and only alternate tracks receive such pilot signal. When the recorded tracks are reproduced by a rotary playback head having a tracing width that is greater than the width of the track, the pilot signals from the adjacent tracks will be detected and can be compared in level, with the comparison output being used to control the tracking of the rotary playback head.

Abstract: PROBLEM TO BE SOLVED: To provide a recording device suitable when a recording/playing-back system to be used for a music is extended to the use for the data recording/reproducing operation. SOLUTION: In the recording device a sector whereon the control information for controlling the recording/reproducing of data is recorded, and a sector to be used for the recording/reproducing of the data are prepared, and also headers furnished with at least the address information and the category information are provided on the sector whereon the control information becoming an allocation table and a directory for controlling the recording/reproducing of the data with respect to a recording medium as the control information are recorded, and on the sector to be used for the recording/reproducing of the data, and this recording device corresponds to the recording medium arranged so as capable of identifying that at least the sector is a free sector without recorded data as the above category information. By rewriting this category information to a code showing the free sector, the sector of data or the sector of control information is erased. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide a recording device suitable when a recording/playing-back system using for a music is extended to the use for the data recording/reproducing operation, and also to provide a reproducing device. SOLUTION: This recording device is adaptable to a recording medium whereon the control information for controlling the recording/reproducing of the data is recorded. When a data file is recorded on the recording medium, an identification code showing the control information for the data file control is recorded on a prescribed area in the control information at the recording or rewriting time of the control information for controlling this data file.

Abstract: PROBLEM TO BE SOLVED: To provide a reproducing method, a recorder and a reproducing device which are adaptive to a recording medium (disc) on which data is recorded, can record/reproduce both of audio data and general data , are suitable for miniaturization and power saving and further prevent the use of a magneto-optic disk obtained by an illegal copy. SOLUTION: First management information in a management area following a pit area on a disk and second management information for general data file management at the disk innermost circumferential side of a recording area of a general data file are provided as reproducing operation management information which records/updates an audio data or general data file and is for the audio data or general data file. Track management is performed with the first management information, and data track management is performed with the second management information. In addition, third management information for managing a general data file that is not managed with the first and second management information as a reproduction object is provided. Recording/reproduction using the third management information is carried out. Copy guard data is recorded in the third management information. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To provide a reproducing device which corresponds to a recording medium (disc) for recording data, is used for both audio data and general data to be able to record/reproduce data, is suitable for miniaturization and power saving and further prevents the use of an illegal copy. SOLUTION: A data management structure provided with first management information on the recording medium and second management information that is physically arranged at the first position in a general data file recording area and is for managing a general data file is formed as management information for managing a reproducing operation of an audio data or general data file. As a reproducing device that corresponds to a recording medium, wherein specific keyword information is recorded in an area managed as a defective area in the first management information and/or the second management information, a defective area shown in the first management information and the second management information is retrieved, keyword information is read, and processing to be carried out is selected in accordance with the existence/absence of keyword information to be read out and contents of read keyword information.

Abstract: PROBLEM TO BE SOLVED: To provide a disk-like recording medium as a recording and reproducing system which can be commonly used as musical applications and general data applications. SOLUTION: Management information (U-TOC) for audio data and management information (U-TOC) for general data are independently provided. At this time, the management information for audio data is formed to have the management information which can identify and manage audio data areas and general data areas. The management information for the general data is provided with the management information to prohibit the recording and reproducing operation for the audio data areas, by which the segments used as the audio data areas among the areas for recording/reproducing of the disk- like recording medium and the segments used as the general data areas can be distinctly managed.
