Data Recovery As leaders in the field DPTS have an enviable reputation as the data recovery and transcription experts. We maintain equipment for reading 7-track,9-track,21-track & analogue tapes and a wide range of cartridges. For a full list of the media we can handle click on Media Capabilities. DPTS have pioneered the investigation of media decay, commonly referred to as stiction, and have developed various methods for data recovery from old media. Stiction occurs when magnetic tapes decay over a period of time, causing the oxide coating to separate from the polyester backing tape. The tape becomes sticky and can stick to the read/write heads causing damage to the drive and loss of data.   Using techniques, specialist equipment and software developed by DPTS we are able to recover data successfully in cases where others fail DPTS are also able to recover data from tapes with skew errors. We maintain specialist tape drives which allow the Operator to adjust the skew of the read/write head manually for optimum recovery of data.
