Method for writing and reading data to and from a compact disc media

A method for writing a file of data to a compact disc media, comprising:

• receiving a first portion of the file for writing to the compact disc media;
• dividing the first portion of the file into a plurality of chunks;
• generating a map data sector for a set of the plurality of chunks, the map data sector including information for interrelating the file data and the plurality of chunks to be written to the compact disc media;
• writing the map data sector to the compact disc media;
• and
• writing the plurality of chunks of the first portion of the file to the compact disc media, the method further including,
• receiving a second portion of the file for writing to the compact disc media;
• dividing the second portion of the file into a plurality of chunks;
• generating a map data sector for a set of the plurality of chunks;
• writing the map data sector to the compact disc media, the map data sector for the set of the plurality of chunks associated with the second portion is logically written after the map data sector for the set of the plurality of chunks associated with the first portion;
• and
• writing the plurality of chunks of the second portion of the file to the compact disc media logically after the plurality of chunks of the first portion of the file.

A method for writing file data to a rewritable compact disc media, comprising:

• receiving the file data in an out-of-order sequence for writing to the rewritable compact disc media;
• receiving a first portion of the file data;
• dividing the first portion of the file data into a plurality of chunks;
• generating a plurality of map data sectors, such that one map data sector is associated with a set of the plurality of chunks, the plurality of chunks including one or more sets of the plurality of chunks;
• writing the plurality of map data sectors to the rewritable compact disc media beginning at a zero file offset;
• and
• writing the plurality of chunks of the first portion of the file data to the rewritable compact disc media, wherein additional plurality of chunks for any additional portions of the file are written consecutively and any additional map data sectors for the additional plurality of chunks are grouped to be written before all of the plurality of chunks, and wherein each map data sector is directly associated with its plurality of chunks.

A method for writing file data to a rewritable compact disc media, comprising:

• receiving the file data in an out-of-order sequence for writing to the rewritable compact disc media;
• receiving a first portion of the file data;
• dividing the first portion of the file data into a plurality of chunks;
• generating a plurality of map data sectors, such that one map data sector is associated with a set of the plurality of chunks, the plurality of chunks including one or more sets of the plurality of chunks;
• writing the plurality of map data sectors to the rewritable compact disc media beginning at a zero file offset;
• and
• writing the plurality of chunks of the first portion of the file data to the rewritable compact disc media at a location that is logically after the plurality of map data sectors, the method further including,
• receiving a second portion of the file data;
• dividing the second portion of the file data into a plurality of chunks;
• generating a plurality of map data sectors;
• writing the plurality of map data sectors associated with the second portion to the rewritable compact disc media at a logical location that is after the map data sectors of the first portion;
• and
• writing the plurality of chunks of the second portion of the file data to the rewritable compact disc media at another location that is logically after the plurality of chunks of the first portion.

A computer readable media having program instructions for writing file data to a rewritable compact disc media, the operations of the computer readable media comprise:

• program instructions for receiving the file data in an out-of-order sequence for writing to the rewritable compact disc media;
• program instructions for receiving a first portion of the file data;
• program instructions for dividing the first portion of the file data into a plurality of chunks;
• program instructions for generating a plurality of map data sectors, such that one map data sector is associated with a set of the plurality of chunks, the plurality of chunks including one or more sets of the plurality of chunks;
• program instructions for writing the plurality of map data sectors to the rewritable compact disc media beginning at a zero file offset;
• and
• program instructions for writing the plurality of chunks of the first portion of the file data to the rewritable compact disc media, wherein additional plurality of chunks for any additional portions of the file are written consecutively and any additional map data sectors for the additional plurality of chunks are grouped to be written before all of the plurality of chunks, and wherein each map data sector is directly associated with its plurality of chunks.

A method for writing file data to an optical storage media, comprising:

• receiving the file data in an out-of-order sequence for writing to the optical storage media;
• receiving a first portion of the file data;
• dividing the first portion of the file data into a plurality of chunks;
• generating a plurality of map data sectors, such that one map data sector is associated with a set of the plurality of chunks, the plurality of chunks including one or more sets of the plurality of chunks;
• writing the plurality of map data sectors to the optical storage media beginning at a zero file offset;
• and
• writing the plurality of chunks of the first portion of the file data to the optical storage media, wherein additional plurality of chunks for any additional portions of the file are written consecutively and any additional map data sectors for the additional plurality of chunks are grouped to be written before all of the plurality of chunks, and wherein each map data sector is directly associated with its plurality of chunks.
