As leaders in the field, Petrographics have an enviable reputation as data recovery and transcription experts, using these techniques, specialist equipment and software. We are able to recover data in the most challenging situations. Petrographics has pioneered the investigation of tape media status as a result of the storing conditions and age, may cause sticking, loosing of magnetic materials, or miss positioning of the recorded data. The tapes that are affected by physical damage, weak magnetic susceptibility, or skew alignment problems need special treatment to develop data recovery. Petrographics is committed to develop data recovery from the affected tapes using special techniques of tape cleaning and extended heat treatment designed to improve adhesion of the metal oxide to the tape-backing medium. We can 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.
