Petrographics has been providing data transcription and data conversion services for more than 20 years. Our unique systems and software protect data during conversion and processing. With our specialized data conversion and data transcription software and procedures, large volumes of low density data from media such as 9 and 21 track tapes, 3480/3490/3490E cartridges, 4mm DAT, 8mm Exabyte and 3590 cartridge can be transferred (with or without conversion of formats) to a wide range of high density media. Our workflow model is designed to ensure the integrity of your data and its long-term security. All tapes in our possession are bar coded and tracked throughout the process and are held in our secure and protected fireproof storage facility
