Used Magnetic Media Data Erasure & Data Security

Download With increasing budgetary pressures, data center managers may be tempted to recoup some of their tape investment by reselling magnetic tape cartridges which are no longer needed. The methods tape resellers use in attempts to remove the original owner's data vary widely, and are largely unsuccessful. New data erasing devices are being touted as having the ability to eliminate original customer data while leaving the servo guiding signals of higher capacity cartridges intact. Imation's laboratory investigation shows that while some of the original data can be removed by these processes, original customer data still remains and is at risk should carts be resold. No practical method exists which can completely erase user data while leaving servo guiding tracks undamaged.
