Abstract: Provided is an adaptive data recording method of recording data in a storage medium using a file allocation table (FAT) file system by a data recording device, the method includes: receiving the data; creating at least one file in which the data is recorded, configuring a cluster chain by sequentially connecting cluster addresses according to an FAT of the storage medium, and recording the data at a actual position of each cluster address; when a file termination interrupt occurs, terminating the file by terminating the cluster chain of the file under data recording, creating a new file, configuring a new cluster chain, and continuously recording the data; and if a residual capacity of the storage medium is less than a predetermined spare capacity when creating a new file, selecting at least one file which is terminated after previous data recording, and continuously recording the data reusing the cluster chain of the selected file.
