1. A system for recording management information on a recording medium, the recording medium including at least one temporary management area for storing management information before the recording medium is finalized, the at least one temporary management areas being used in a designated order, the system comprising:
- a recording device adapted to record data on the recording medium, the recording device including;
a pickup unit adapted to record management information in each of the at least one temporary management areas, and to create at least one access indicator indicating which of the at least one temporary management areas is currently available for use, anda microcomputer coupled to the pickup unit and configured to control the pickup unit to create an access indicator in one of the at least one temporary management areas when temporary management areas become available; and
a host device, operatively coupled to the recording device via an interface, configured to transmit to the recording device a write command for recording data onto the recording medium.
