Abstract

We propose a three-step modular approach to recover data from Compact Disc (CD) fragments. The basic idea is to simulate the effect of an optical read-write system. A high power microscope is used to capture a series of contiguous image frames and recover a derived electronic signal, which is similar to the actual signal that is detected in conventional systems. Real data bytes are recovered from this derived electronic signal using signal processing techniques. Finally, data descrambling is performed to determine the user sequence of these recovered real data bytes. The procedure to recover the Absolute Time In Pre-groove (ATIP) information from the real data bytes is also presented. Statistical analysis of the probability of recovering ATIP information from a CD is illustrated using experimental data. A benchmark is provided for the minimum CD track length that is required to partially or completely recover the ATIP information.
