Abstract
The configuration of a microcomputer to be used as the control device of a medium reading apparatus is such that writing unit by unit into and erasion block by block from a prescribed area, such as a user data storage area, in a nonvolatile memory built into the microcomputer makes possible, if any writing into the user data storage area is needed, for data to be successively written while updating the units, data included in the prescribed area to be erased when all the units have been written into, and the next data to be written into the erased blocks.
