PROBLEM TO BE SOLVED: To provide a reproducing unit for medium that has 10 thousands of repeat counts of rewrite guarantee, because of being insufficient for repeat count of rewrite in conventional micro computer integrated flush memory with about a hundred of repeat counts of rewrite guarantee. SOLUTION: A predefined area like an user data storage area of nonvolatile memory that is integrated into a micro computer used as a control device of reproducing unit for medium is composed so as to write at each unit and so as to delete at a block unit. And when writing processing to user data storage area broke out, the data are written sequentially with updating the said unit, or when wiring processing to all units broke out, the data included in the said predefined area are deleted, and the predefined area is also composed so as to write next data to the deleted block. |
