Abstract

Abstract A video disk recorder for executing a real-time edition records desired scenes to a disk while allowing an operator to observe a relay video image that is currently in progress. In response to the generation of a recording command signal, a recording head is set to a recording mode and a disk address of the recording head at that time is stored as a determinate disk address. In response to the generation of a stop command signal, the recording mode is canceled and a disk address of the recording head at that time is stored as a temporary disk address. In the case where a skip command signal is generated during the recording mode, the recording head is moved to the determinate disk address stored at the time of the start of the recording mode. In the case where the skip command signal is generated in a mode other than the recording mode, the recording head is moved to the temporary disk address.
