Data Recovery Specialists with their extensive knowledge of recovery of data from most data storage devices including Hard Drives, RAID, Optical Disks and Magnetic Tape have been approached by several large multinational organizations to recover the voice data from their legacy voice logging archives stored on DDS2 magnetic tape cartridges using Racal WordNet 2.0 into GSM.WAV format, compatible with Microsoft's Industry standard codec.
Data Recovery Specialists experience of magnetic tape recording dates back to the early 1960's where at Imperial College London and subsequently Racal and Norman Magnetics the development of peripherals as well as magnetic tape and optical disks for the storage of data was undertaken.
The financial services industry has experience several major criminal and civil claims against it in recent years including fall out from the financial crash, PPI, LIBOR and most recently EURIBOR as well as UK and European stress testing and compliance by national and European governments and agencies. This has resulted in the need to examine the voice logged data of telephone conversations built up over decades. Both civil and criminal claims have been made making the accurate retrieval of this archived data essential and of a sufficient standard to hold up in both criminal and civil courts world wide.
Some of this voice logged data was recorded several decades ago and the legacy readers are either no longer available or unsupported by the original equipment manufacturer. There are few companies who have the experience to retrieve this data on behalf of the financial institutions, however Data Recovery Specialists has been at the forefront of Data Recovery from most data storage devices including magnetic tape, hard drives and optical disks since the companies original conception in the early 1990's, and before that at Norman Magnetics and Racal.
By the examination of sample tape cartridges with logged voice data Data Recovery Specialists were able to reverse engineer the software and hardware necessary to read these tapes. It was not only necessary to read this data but also to ensure it was presented in such a way that the financial institution could integrate it and present it as evidence to the relevant courts.
One of the first formats to be reversed engineered was the Racal Wordnet 2.0 format written on to DDS 2 magnetic tape cartridges. The voice data was extracted and the date, time and origination details of this voice data was encrypted at the start of each file in a format requested by the customer. This data extracted from the voice logging tapes was of sufficient quality and presentation to be admissible in the relevant courts, stress testing and compliance exercises.
With the expertise in tape formats and hardware Data Recovery Specialists have developed the capability to reverse engineer most legacy voice logging systems no matter what medium or format it had been originally encoded.
A further spin off from the retrieval of the undamaged but inaccessible voice logged data is the ability to use the propitiatory facilities of DRS to recover data from damaged or age deteriorated magnetic tapes left in an uncontrolled environment. Data has been successfully retrieved from snapped tape cartridges as well as layer to layer adhesion causing the magnetic tape surface to be stripped from the original polyester base leaving large clear windows in the tape. As with most archived tape libraries there is normally a percentage of tapes where the data is irretrievable.
