Abstract: PURPOSE:To easily recognize pictures and to improve a using feeling by connecting picture data for retrieval on a front side inside a data file to the picture data, forming them as one unit of the data file and changing the display state to a moved display range. CONSTITUTION:Broken lines indicate the dot size of a display part and only a slight area can be displayed by one screen in a normal picture 60, however, more than a half of the area can be displayed by one screen in a thinned picture 50. When the display of the thinned picture 50 is viewed and the pictures are desired to be displayed in detail, the normal picture 60 is displayed. Since the thinned picture 50 and the normal picture 60 are in the same data file, the time is not required for changeover. Then, when the dot size of the picture data is larger than a displayable size, a large range approximately for one screen for instance is moved (jumping movement) and the whole is promptly confirmed. Further, by minutely adjusting a display position so as to make a target part easily visible by shift movement, usability is improved.

Abstract: PURPOSE:To easily record and reproduce picture data by connecting the picture data for retrieval on a front side in a data file to the picture data and forming one unit of the data file by both picture data. CONSTITUTION:The frame of broken lines indicates the dot size (640 dots wide and 400 dots long) of a display part. Only a slight area can be displayed by one screen in a normal picture 60, however, more than a half of the area can be displayed by one screen in a thinned picture 50 and the whole can be confirmed by moving a display area within two screens. Also, when it is set to display and output the thinned picture 50 in advance, the thinned picture 50 can be displayed immediately after the specifying operation of a reproducing file. Also, more than a half of the area of pictures is displayed by the display of one time in the thinned picture 50 and it is useful for the retrieval. Also, since the thinned picture 50 and the normal picture 60 are in the same data file, the access operation of changeover is unnecessary and the time is not required.

Abstract: PURPOSE:To provide the recording medium capable of dealing with both of an application for music and an application for general data by providing management information for general data in addition to management information for audio data. CONSTITUTION:The recording medium is provided with the management information (U-TOC) for audio data and the management information (data U-TOC) for general data within the prescribed management area. The U-TOC manages the audio data in a recordable user area from a recordable user area start address RSTA to a read out start address ROA and manages the range of the general data area therein. On the other hand, the data U-TOC manages areas DF1 to DF4 where data files are recorded, an empty area EA and recordable/ reproducible areas WA1, WA2. This data also manages areas PWR1 to PWR4 where recording and reproducing of the data are prohibited.

Abstract: PURPOSE:To divide a series of recording data and to record the divided data in a plurality of data regions by a method wherein a track number table and an address information table are recorded in a read-in region as read-in information. CONSTITUTION:A system controller 7 controls the recording position and the replay position of a recording data with reference to a data region in the recording and replay region of a magneto-optical disk 2; a series of data is divided; the divided data are recorded in a plurality of data regions. The controller 7 generates the following on a TOC memory: a track No. table composed of track No. information which indicates data recorded in the individual data regions; address information which indicates the positions of the individual data regions; and an address information table which indicates a beam of coupling light from one data region to the other data region. The data of the tables ate recorded in the read-in region of a recording and replay region as read-in data.

Abstract: PURPOSE:To enhance the matching of a spindle motor immediately after track jump by providing a speed servo generating means to hold a speed servo signal just before the track jump, and a means to generate a phase servo signal at a prescribed state. CONSTITUTION:A speed servo generation circuit 60 generates the speed servo signal SBVR based on a wobble signal SWB or a data signal FMCK. Also, the circuit holds the signal SBVR just before performing jump in the track jump and drives a spindle motor based on a held signal SBVR after performing the jump. Meanwhile, a phase servo generation circuit generates the phase servo signal SBPH by comparing the phase of the signal SSB or the signal FMCK with that of a reference clock signal CKEFM. Also, the spindle motor is driven by resetting the phase of the signal CKEFM at a prescribed timing immediately after the track jump, and generating a signal SBPH from a state where the phase of the signal SWB of the signal FMCK coincides with that of the signal CKEFM.

Abstract: PURPOSE:To execute the satisfactory reproduction even when the error factor between respective pieces of equipment is considered by time-base-compressing and recording the same signal as a synchronizing signal and the signal such as performance information succeeding to an unevenness pattern for a disk where the synchronizing signal is recorded as the unevenness pattern beforehand. CONSTITUTION:A recording disk 1, for example, is an optical magnetic disk having a vertical magnetizing film having a magnetic optical effect and rotated and driven with a constant linear velocity. A pregroup 2 is formed in a spiral shape on the disk 1, and on the land part between groups 2, an emboss area 4 composed of the unevenness pattern by a pit 3 in an inner circumferential direction and a signal recording area 5, in which an optical magnetic recording is executed, are alternately provided at an equal pitch. At the area 4, the parts of 44 bits in total of a frame synchronizing signal and a sub-code are recorded beforehand. At the area 5, 588 bits of the same signal as the area 4 and the signal such as performance information are time-base-compressed and recorded. Thus, even when the error factor between respective pieces of equipment at the time of recording and reproducing is considered, a satisfactory reproduction can be executed.

Abstract: PROBLEM TO BE SOLVED: To surely, easily and continuously record the data on another record medium when a free area exists in another record medium even when the free area is not left in the record medium while recording by providing a memory for storing control information of plural record media housed in a device at a device initialization time. SOLUTION: At a system initialization time, a system controller 11 controls a stage controller 33, a loading controller 34, etc., and loads successively MD (MiniDisk) 1a-1e onto a player box 32, and reads TOC information and the head part data recorded on the MD 1a-1e to store them in a RAM 12. After the initialization, the system controller 11 finds what amount of free areas exist in some address position in some MD from the TOC information stored in the RAM 12, and surely and beforehand selects the MD to be recorded continuously next in a very short time.
