Recording medium storing link information and apparatus and method for linking data

A method of linking data, the method comprising:

• dividing an error correction code block having a predetermined size into a plurality of sectors and checking data type identification information which indicates whether data in each sector is linking data;
• and
• replacing main data of a sector with predetermined data according to the result of checking the data type identification information,
• wherein if the data type identification information in sector information is a “1b,” this indicates that the current sector is a linking loss area, and main data recorded in the current sector is replaced with “00h” regardless of the data to be reproduced.

A method of linking data, the method comprising:

• dividing an error correction code block having a predetermined size into a plurality of sectors;
• checking whether data type identification information indicates that data in a current sector is linking data;
• and
• allocating a current sector as a linking loss area if said data type identification information indicates that the data in the current sector is the linking data.
