<p>There is provided a safeguard function to inhibit the information recording on an optical disc which is not contained in a cartridge. This aims at improvement in reliability. Disc detector (401) discriminates whether the disc loaded at tray (101) is a bare disc or a cartridge type disc. When a bare disc is loaded, even if a recording instruction is given, system controller (402) inhibits a start of recording, and displays that fact on display unit (403). Or, in such case, system controller (402) enables a start of recording on another recordable disc. <IMAGE></p> |
