Abstract
Methods of preventing output of noise to a television monitor during existence of unusual conditions in a disk player. In accordance with one such method, when the disk player is reproducing information recorded on a composite disk storing both audio and video information, and a search is conducted which requires the pickup of the disk player to cross a boundary between the two regions on the composite disk, the most recently-reproduced video information stored in a video memory is repeatedly read and reproduced on a television monitor during the search. In accordance with another method, when an off condition of a main power supply is detected, the most recently read video information just prior to detection of the off condition is stored in a video memory, and is repeatedly read out until the disk player has been reinitialized. Additionally, the last known address of the pickup prior to power supply interruption is stored, and the pickup is moved back to that location so that the reproducing operation may be resumed without the need for an additional search by the user.
