PROBLEM TO BE SOLVED: To enable real time recording with stable writing performance. SOLUTION: A recordable memory device includes a nonvolatile semiconductor memory 5, and a controller 4 controlling the nonvolatile semiconductor memory 5 based on a recordable system. The nonvolatile semiconductor memory 5 has a user area capable of directly making an access from a host 1, and a system area managed by the controller 4. Data writing to the reformatted user area of the nonvolatile semiconductor memory 5 executes from a start point which is an unused area after the final physical address of old recordable data recorded in the user area just before the reformat. The data writing sequentially executes from a start point which is a top physical address in the user area, when the start point exceeds the final physical address in the user area.
