Abstract
Embodiments of methods and systems for controlling access to information stored on memory or data storage devices are disclosed. In various embodiments, fluid-mediated modification of information or access to information is utilized. According to various embodiments, data storage devices designed for rotating access are described which include rotation-activated fluid control mechanisms.
Claims26
A limited use memory device comprising:
- a substrate;
- machine-readable data stored on said substrate;
- and
- at least one centrifugally activatable switching mechanism on said substrate, said switching mechanism configured to produce modification of a feature of the memory device.

A disk drive system, comprising:
- a receptacle for receiving a substrate configured for rotating access having stored data and a rotation activatable switching mechanism thereon;
- a read head for reading data from the substrate;
- a motor capable of spinning the substrate in a controlled pattern in response to a control signal;
- and
- a drive controller including electrical circuitry configured to generate a control signal for causing said motor to spin said substrate in a controlled pattern sufficient to produce activation of said rotation activatable switching mechanism.

A computer system comprising:
- a processor;
- a system bus;
- an input device;
- an output device;
- a drive capable of reading data from a substrate configured for rotating access;
- and
- data storage media containing software instructions capable of controlling said drive to produce rotation of the substrate of intensity and duration capable of activating a rotation activatable mechanism to render at least a portion of machine readable data stored on the substrate inaccessible.
