Abstract
The data destruction machine is a desk-top, portable unit with a short (under 10 second) cycle time, pluggable into a wall outlet. Upon insertion of a disk (such as a CD or split DVD) into the machine, which is fully automatic, data is removed. The machine converts the data-storage layer into residue consistent with security destruction standards from which no data is retrievable. A single machine may be used for declassifying CDs and split DVDs. Splitting DVDs in preparation for inserting them into the data destruction machine may be accomplished quickly and simply.
Claims8
A method for security declassification of a disk having at least one interior information-bearing surface, comprising
- lengthwise-splitting the to-be-split disk into a number of thinner split-disk fragments;
- and,
- contacting each interior surface of the split-disks with a rotating cutter having a patterned surface to provide a declassified disk surface.
A high-security, high-speed DVD declassification machine, comprising:
- a patterned-surface cutter;
- a motor connected to the cutter for rotating the patterned-surface cutter at 10,000-30,000 rpm;
- and
- a system for capturing and positioning a lengthwise split half-DVD to press the rotating patterned-surface cutter parallel to the DVD surface with the cutter length aligned with a disk exterior ring radial length for sweeping the disk external data surface.
