<p>A disc player, for reproducing program information from a disc on which the information is recorded as digital program information data accompanied by digital address data, comprises an optical reader for reading program information data and address data from the disc, such reader being selectively operable in a searching mode and in a playback mode, processing circuitry supplied with program information data to produce program information from the program information data, a detecting means that compares designated address data identifying desired program information with the reproduced address data in the output of the reader and system controlling means for controlling the reader to continue the searching mode until the reproduced address data match the designated address data, at which time the system controlling means operates the reader in its playback mode to read from the disc the program information data identified by the designated address data. Noise-suppressing means substantially prevents the processing circuitry from producing program information from the program information data in the output of the reader operating in the searching mode. The clicking noises and other spurious sounds produced by prior art disc players from the program information data read during the searching mode are thus prevented from occuring before the production of desired program information from the disc.</p> |
