Abstract

A recording apparatus records, in a recording medium, moving image data and management information, concerning the moving image data and generated in accordance with the recording operation of the moving image data. In accordance with a recording start instruction, the recording apparatus starts recording of the moving image data and records, in the recording medium, information indicating that the management information has not yet been recorded. In accordance with a recording stop instruction, the recording medium stops recording of the moving image data, generates and records the respective management information, and updates the information indicating the recording status of the management information. If a decrease in electric power is detected during recording of the moving image data, the recording apparatus stops recording of the moving image data, without updating the information indicating the recording status of the management information.

Claims9

Dependent claims

A recording apparatus comprising:

a recording unit that records in a recording medium moving image data and a management information concerning the moving image data recorded in the recording medium, the management information having an attribute information of the moving image data, the moving image data recorded in the recoding medium being reproduced in accordance with the attribute information;
a CPU that controls the recording unit so as to record the moving image data in the recording medium in accordance with a recording start instruction and to stop recording the moving image data in accordance with a recording stop instruction,
wherein the CPU generates the management information in accordance with the recording operation of the moving image data by the recording unit;
wherein the CPU controls the recording unit, in accordance with the recording start instruction, to record the management information having the attribute information having a predetermined value indicating that the management information is not updated, and
wherein the CPU controls the recording unit, in accordance with the recording stop instruction, to update management information recorded in the recording medium such that the management information recorded in the recording medium has the attribute information having a value different from the predetermined value.

2 more elements

A recording apparatus comprising:

a CPU;
a recording unit that records in a recording medium moving image data and a management information concerning the moving image data recorded in the recording medium having a recording area for the management information, the recording unit recording the management information in the recording area for the management information;
a generating unit that generates the management information in accordance with the recording operation of the moving image data by the recording unit;
and
a memory that stores the management information generated by the generation unit;
a controller that controls the recording unit so as to record the moving image data in the recording medium in accordance with a recording start instruction and to stop recording the moving image data in accordance with a recording stop instruction;
a power supply unit,
wherein the controller controls the generating unit and the recording unit such that in accordance with the recording start instruction, a predetermined portion of the management information is set to a predetermined value representing that the management information is not updated and the management information having the predetermined portion set to the predetermined value is recorded in the recording area for the management information,
wherein the controller controls the generation unit and the recording unit in accordance with the recording stop instruction, to update the management information recorded in the recording area for the management information such that the predetermined portion of the management information recorded in the recording medium has a different value from the predetermined value, and
wherein if a decrease in electric power from the power supply unit is detected during recording of the moving image data, the controller controls the recording unit so as to stop recording the moving image data without updating the management information recorded in the recording area for the management information and record the management information stored in the memory in a recording area of the recording medium other than the recording area for the management information,
wherein the generating unit and the controller are implemented by the CPU.
