摘要： A polling system for use in an audio system in which a plurality of controllers for controlling a plurality of input/output devices of the audio system and a system controller for controlling the status of the plurality of controllers are connected via a bus line. In an initial polling operation upon power-up of the system, the system controller in order confirms the connection of the plurality of controllers to the system and stores the results of confirmation. When the absence of connection of the controllers is confirmed in the initial polling operation, the system controller further monitors the level on a transmission line provided in the bus line for transmitting a requesting signal from the plurality of controllers to the system controller, and performs the polling operation once more if the presence of the requesting signal is confirmed.

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： 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.
