Data in each predetermined unit recording area on a rewritable information recording medium can be managed, without an increase in the production cost of the disclosed information recording and reproducing device. Upon receipt of a user data write instruction from a host device, the device CPU updates the contents of a management table. User data transmitted from the host device are then written and recorded, and the user data write operation comes to an end. In this manner, the CPU updates the contents of the management table on the information recording medium before writing user data.
