Magnetic force microscopy (MFM) has been used to investigate the potential for retrieving information from an erased or altered audiotape. The audiotape recording process, the reasons for the distortion of signals during the recording process are presented. An in-depth study has been conducted to investigate the effects of MFM operation parameters on the data retrieval process. Most importantly, these include interleave height and tip speed. Interleave height (i.e., the height of the MFM tip above the surface) has been optimized for maximum clarity of MFM images. Tip speed studies have been carried out to optimize the data retrieval time and suggestions to further reduce the retrieval time are also made. A study has also been performed using MFM to determine the maximum frequency that could be recorded on an audiotape. This optimization of MFM suggests a novel technique for the retrieval of data from erased or altered audiotape.
