Abstract
The present invention relates to a mobile device for destroying data carriers, such as hard disks. The mobile device according to the invention may include clamping means for inhibiting and/or preventing pieces of disk from being pulled out of the hard disk during the cutting. The invention also provides a corresponding method.
Claims18
A mobile device for destroying a hard disk, which hard disk comprises a plurality of platters concentrically placed around a drivable shaft, the mobile device comprising:
- a cutting device having a first knife connected to a driver for the purpose of completely cutting through the hard disk;
- a feed channel, elongated in a feed direction, through which the hard disk can be moved towards the cutting device by means of a feed device, wherein the feed device is disposed and adapted for the purpose of stepwise feeding the hard disk in the feed direction to the cutting device, wherein a step size of the stepwise feeding is preferably adjustable;
- clamping means for preventing pieces of platters from being pulled out of the hard disk during the cutting which are too large;
- wherein the cutting device is arranged to cut the hard disk substantially perpendicular to the feed direction;
- wherein the clamping means comprise at least two blunt protrusions, wherein a width of the feed channel and the arrangement of the blunt protrusions is such that, during operation, the at least two blunt protrusions can engage the hard disk on either side of the driving shaft and wherein the protrusions are configured for deforming and clamping the platters in the hard disk or in the remaining part thereof prior to the completely cutting through the hard disk.
A method for destroying a hard disk, which hard disk comprises a plurality of platters concentrically placed around a drivable shaft, wherein the method comprises the steps of:
- stepwise feeding the hard disk in a feed direction to a cutting device which comprises a drivable first knife;
- and
- driving the first knife for the purpose of completely cutting through the hard disk substantially perpendicularly to the feed direction;
- clamping the hard disk in order to prevent pieces which are too large being pulled out of the hard disk during the cutting;
- the clamping comprising engaging the hard disk with at least two blunt protrusions on either side of the driving shaft to thereby deform and clamp the platters in the hard disk or in the remaining part thereof prior to the complete cutting through of the hard disk.
