Optical recording/reproducing apparatus and data recording method thereof

A data recording method, comprising:

• allocating a specified area of an optical recording medium loaded in an optical recording and/or reproducing apparatus as a management information record area;
• encoding data for recording in a specified format;
• recording the encoded data into a data recording area of the optical recording medium, and recording management information regarding the data being recorded in the allocated management information record area;
• and
• periodically copying the management information of the management information record area into a file information record area of the optical recording medium.

An optical recording/reproducing apparatus, comprising:

• an encoder which encodes a data for recording in a specified format;
• an optical pickup which records the encoded data onto a data record area of an optical recording medium which is loaded in the optical recording/reproducing apparatus;
• and
• a controller which controls the optical pickup to record management information regarding the data being recorded in the data record area in a management information record area which is in a hard disc drive (HDD), and to copy the management information of the management information record area onto a file information record area of the optical recording medium.

A data recording method comprising:

• encoding data for recording in a specified format;
• recording the encoded data in a data recording area of an optical recording medium loaded in an optical recording and/or reproducing apparatus, and recording management information regarding the data being recorded in a management information record area in a hard disk drive (HDD);
• and
• periodically copying the management information of the management information record area onto a management information file which is recorded in a file information record area of the optical recording medium.

A data recovery method, comprising:

• determining whether a flag is set, the flag being set when a recording operation of the data has not been successfully completed, the flag not being set when the recording operation of the data has been successfully completed;
• reading management information from a medium based on the determining;
• and
• reproducing the data from the medium using the management information,
• wherein management information is read from a file information record area of the medium when a recording operation of the data has been successfully completed and from a management information record area of the medium when a recording operation has not been successfully completed.

A data recovery method, comprising:

• determining whether a flag is set, the flag being set when a recording operation of the data has not been successfully completed, the flag not being set when the recording operation of the data has been successfully completed;
• reading management information from a medium based on the determining;
• and
• reproducing the data from the medium using the management information,
• wherein management information is read from a file information record area of the medium when a recording operation of the data has been successfully completed and from a management information record area of a hard disk drive (HDD) when a recording operation has not been successfully completed.

A recording medium, comprising:

• a data record area having a management information record area in which is temporarily stored management information regarding a data stream being recorded in the data record area, the management information recorded in the management information record area is updated to the file information record area every time the record of one title is completed;
• a lead-in area including therein a list of information about the data recorded in the data record area;
• a file information record area including therein a management information file to manage the data files recorded in the data record area;
• and
• a lead-out area including an information indicating the end of the recorded data of the data record area.

A hard disk drive, comprising:

• a data record area having a management information record area which temporarily stores management information regarding a data stream being recorded in the data record area, the management information being updated onto a file information record area of a recording medium every time a recording operation is completed for a title, an area of the management information record area being allocated as a record flag setting area to indicate normality or abnormality in the recording operation;
• a boot record area including information about the partitioning of the data record area;
• a FAT area including information regarding cluster position and status of the data stream recorded in the data record area;
• and
• a root directory area including attribute information and position information of the data recorded in the data record area,
• wherein the record flag is set when the recording operation is started, and reset upon completion of the recording operation.
