Method for copying, recording, and editing data onto disk recording media, and disk recording apparatus

A method for editing data in a disk recording medium, wherein a data recording area of the disk recording medium is divided into multiple consecutive access blocks with a specified block length;

• (K−1) number of access blocks filled with data in K number (K is an integer number) of access blocks is predetermined;
• and,the presence of (K−1) access blocks filled with data before an edit start point of a source data to be edited is checked at editing data for executing the next operations:
• i) if the presence of (K−1) access blocks is confirmed, data is edited from the edit start point;
• and
• ii) if the presence of (K−1) access blocks is not confirmed, data is packed to the end of an access block not filled with data to make it a full access block, and then data is edited from the edit start point.

A method for editing, data in a disk recording medium, wherein a data recording area of the disk recording medium is divided into multiple consecutive access blocks with a specified block length;

• the access block length for consecutively recording data and (K−1) number of access blocks filled with data in K number (K is an integer number) of access blocks are predetermined;
• and the presence of (K−1) access blocks filled with data after an edit end point of a source data to be edited is checked at editing data for executing the next operations:
• i) if the presence of (K−1) access blocks is confirmed, data before the edit:
• end point is edited;
• and
• ii) if the presence of (K−1) access blocks is not confirmed, data is packed to the end of an access block not filled with data to make it a full access block, and data before the edit end point is edited.

A data editing apparatus for a disk recording medium comprising:

• a memory for storing data;
• recording means for recording data onto an external recording medium;
• and
• a memory controller for editing data stored in the memory and transferring it to the recording means;
• said memory controller comprising:
• an edit data accumulator for storing edit data;
• an access block searcher for searching access blocks of data stored in the edit data accumulator;
• an editor for recording data in each access block;
• and
• an edit controller for determining the access block length for consecutively writing data and (K-l) number of access blocks fully recorded with data in access blocks, and controlling access block searching and data editing operations;
• said access block searcher comprising:
• a K block holding means for shifting and storing data read out from the edit data accumulator for each access block;
• and
• a block monitor for monitoring the presence of two and more access blocks in which data is not fully recorded in K access blocks held in the K block holding means.
