A disc device in which recording is possible in a basic recording area in units of a subarea and startable at any position. Even if the recording cannot help stopping due to some external cause during recording on a disc-type recording medium that basically employs real-time sequential recording, the recording is re-openable at the position where the recording stopped when the external cause has disappeared. The disc device includes a reference clock counter that starts to count at the starting point of each basic recording area reference clocks read from the disc, and an address memory that holds an address of the basic recording area under recording. When the recording is stopped due to some external cause, the count of the counter and the address held by the address memory at that time are saved.
