CONTROL DEVICE, CONTROL METHOD, RECORDING DEVICE, AND RECORDING METHOD

摘要

A control device (610) controls recording of data on an information recording medium on which the number of data rewrite times in the same area is limited. The control device (610) judges whether the data to be recorded is real time data or non-real time data (S1). When the data to be recorded is judged to be real time data, the real time data is cyclically recorded on a second area pre-defined in a first area assigned in advance in the information recording medium (S2 to S5). When the data to be recorded is judged to be non-real time data, an unassigned area is searched from a predetermined address in the first area, and the non-real time data is recorded in the unassigned area found by the search (S6, S7). The search of the unassigned area for recording the non-real time data is also performed in the second area in the first area (S6).
