Patent ID: 8301011

Claim:
A portable recording apparatus for recording data onto an optical recording medium by optical recording, comprising: an optical pickup unit configured to write said data onto the optical recording medium; a vibration detector configured to detect, at all times, a vibration applied to said portable apparatus; a controller configured to control a finalize process for enabling another reading apparatus to read said written data on the optical recording medium; an input unit configured to instruct the controller to perform said finalize process based on a finalize-process instruction from a user, wherein the finalize-process instruction initiates a start of a repeatable predetermined time period; and a display to notify the user of predetermined information, wherein said controller notifies said user of said predetermined information, by said display, to request said user to keep said portable recording apparatus stable during said finalize process; and said controller starts writing data that relates to said finalize process onto said medium by said optical pickup unit only when no vibration is detected by the vibration detector during the repeatable predetermined time period that starts after reception of the finalize-process instruction from the user to perform said finalize process.
