摘要： An apparatus for automatically performing channel change of a television receiver using a video cassette recorder includes a playback command detector for detecting a playback command, a channel sensor for sensing a video viewable channel which is selected by a radio frequency changeover switch according to a user's selection, a memory for storing the video viewable channel sensed by the channel sensor, television receiver channel change data and television receiver codes corresponding to different types of the television receiver, a controller for reading one of the television receiver channel change data stored in the memory corresponding to the video viewable channel sensed by the channel sensor upon the detection of the playback command by the playback command detector, and a remote transmitter for remotely transmitting the television receiver channel change data from the controller to the television receiver to change a current channel of the television receiver to the video viewable channel sensed by the channel sensor in a playback mode of the video cassette recorder. According to the invention, the current channel of the television receiver can automatically be changed to the video viewable channel upon input of a playback key signal or insertion of a video tape into a deck of the video cassette recorder.

摘要： A method for replacing a defective block with a good block in an optical disk allows data recording operations to be effectively performed. The method temporarily stores data that would have otherwise been recorded in a defective area of an optical disc in a temporary buffer. The method then stores the data in the temporary buffer in a spare area of the optical disc after the normal data recording operation is completed, or if the amount of data in the buffer exceeds a predetermined memory capacity. The method can continuously and quickly perform a general data recording operation, effectively avoid a system load increase due to frequent track movements on an optical disc, and appropriately record real-time data without the loss of data.
