The invention provides a recording/reproducing device which records management data unifying front and back sides. A management data input/output processing section reads data from a front side of an inserted recording medium, a management data creation section creates management data on the front side and temporarily stores it in a memory section. After prompting the user to turn over the recording medium, the device checks the turnover of the disk, and reads data on the back side and creates management data. The management data creation section creates unified management data which unifies the management data on the double-side and the unified management data is wrote onto the back side of the recording medium. When writing is completed, the device prompts the user to turn over the recording medium and records, upon recognizing that it is the front side, the unified management data onto the front side.
