Patent ID: 7424200

Claim:
An optical information recording apparatus, comprising: a first portable electric power source; a first detector circuit for detecting remaining capacity of said first electric power source; an external power source terminal of a second electric power source, being connected to an outside; a second detector circuit for detecting that the second electric power source is supplied to said external power source terminal; a recording circuit for recording information on a removable optical recording medium; a finalizing process circuit for executing a finalizing process for said optical recording medium, the finalizing process making the optical recording medium to be compatible with a read-only disc, wherein the finalizing process circuit is configured to execute the finalizing process for a predetermined time period; and a display for providing a first indication of the predetermined time period, wherein the first indication is provided on the display before the finalizing process is initiated, wherein when either one of the remaining capacity of said first electric power source or voltage of said second electric power source is detected to be equal to or higher than a predetermined value, in said first detector circuit and said second detector circuit, the finalizing process is initiated by said finalizing process circuit upon said optical recording medium.
