Current digital music file duplication software only detects the duplication of digital music file in the hard disk of a personal device 1, 2. This study develops a biologically inspired model for storing audio data (BiMSAD) to prevent duplication of digital music files when the data are inserted into the hard disk. This paper presents the activities in developing of the theoretical and conceptual frameworks. Experiments testing are performed to show the usability of BiMSAD and the results are reported. The outcomes of BiMSAD indicate that it prevents duplication of digital music files in a personal device better than the existing methods which only detect duplication after it occurs. The hard disk of personal device can be controlled and optimized for extra digital music record collection by BiMSAD. © 2006-2015 Asian Research Publishing Network (ARPN).
