摘要： Disclosed is a CD player that ensures a setup operation and reproduction of information even when a partially recorded CD-R is set therein. The CD player sequentially performs the setup operation, starting from the first setup position located at the innermost periphery of the CD, predetermined for the setup operation, until the setup operation is complete at any of n-th (n=2, 3, . . . ) setup positions lying outwardly of the first setup position. If the setup operation is not completed even at an n-th setup position located at the outermost periphery of the CD, the CD player performs the setup operation again at at least one setup position lying inwardly of the n-th setup position. Also disclosed is a CD player that can discriminate a partially recorded, additionally recordable CD-R, and can execute the reproduction control for the PRD. This CD player discriminates a set disk as an additionally recordable one when a mirror-finished portion is detected in the control to detect the lead-in area or when the lead-in area cannot be detected and the TOC information cannot be read.

摘要： A playing apparatus for a compact disc on which TOC information comprising at least first to third point data has repetitively been recorded in a lead-in area. A reading point by a pickup is moved in the lead-in area from the disc outer rim side in accordance with a TOC information reading command. When it is detected that the reading point was positioned to a recording track of third point data locating on the disc inner rim side in each of the TOC information, the reading point is jumped to the disc inner rim side by at least only two tracks. After that, the reading point is moved toward the disc outer rim side along the track, thereby reading the TOC information including the first, second, and third point data.

摘要： A CD player capable of detecting the recording end of a partially recorded CD-R (PRD) during playback. When an unrecorded area (URA) is detected, an address immediately before that of the URA is held and a setup is performed at the position of that detection. If the setup is unsuccessful, a setup is performed at a reference setup position, and when this setup operation is complete, playback starts from the held address position. When the playback from the position and detection of the URA are repeated a predetermined number of times, the held address position is discriminated as the recording end. According to a method of searching for the last piece of recorded information in the program area on a PRD, when reading failure occurs in a search, the pickup is moved back to a previous jump position to the occurrence of the reading failure. Then a search is conducted through a jump over tracks equal to or less in number than the number of tracks of a predetermined smallest amount of information from that jump position, and the last piece (e.g., song) is detected by a sub code acquired at a jump position immediately previous to the re-occurrence of reading failure. A CD player capable of ensuring reproduction of all the pieces of recorded information during playback of a PRD updates the last track number to the newly detected track number when detecting a next track number in an area following an area of a memorized last track number during playback of a PRD.

摘要： Method and Apparatus for playing a CD are designed to allow playback of a partially recorded disk of CD-Rs (CD-Recordable) having the DRAW (direct read after write) capability. It is determined if a target disk is a partially recorded CD-R recording medium. When a reverse command to return to a predetermined address of the recording medium to execute playback is input, the absolute time for information being reproduced is detected and it is then determined if the absolute time is within a predetermined actual pause period. When the absolute time is determined to be within the actual pause period, the reverse command is canceled. It is therefore possible to properly operate a servo system within that recording area of the recording medium where information has already been recorded, thereby allowing a return to a predetermined address associated with the reverse command. This prevents the loss of control of the servo system. When the pickup position is in a lead-in area of the partially recorded CD-R recording medium, thus ensuring the proper reading control.

摘要： A system for storing information representing at least one data item selected for playback from a plurality of data items recorded on a recording medium. The system includes playing back one of the plurality of recorded data items for a predetermined period of time at a fast playback speed which is greater than a normal playback speed used during normal playback of a data item to determine if the data item being played back at the fast playback is to be subsequently played back at the normal playback speed, storing information representing the data item being played back in a memory only if the played back data item is to be subsequently played back at the normal playback speed, and repeating the playing back and storing for each of the plurality of recorded data items so that information representing each of the plurality of recorded data items which is to be subsequently played back at the normal playback speed is stored in the memory.

摘要： An operation mode is first selected in which tunes recorded in a digital audio disk are sequentially reproduced. Reproduction-undesired tunes are selected by operating a manipulator for stopping reproduction of a currently reproduced tune and starting the next tune during every reproduction of the reproduction-undesired tunes so that their numbers are stored in a memory. In subsequent reproductions, the number of each tune going to be reproduced is compared with the numbers of the reproduction-undesired tunes stored in the memory and the tune is skipped if its number is included in the stored numbers.
