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.
Claims29
-15. (canceled)
A data storage device comprising:
- a substrate configured for rotating access;
- a data storage medium capable of storing machine-readable data carried by said substrate;
- a reservoir on said substrate adapted to contain a fluid;
- a fluid responsive region on said substrate configured to receive fluid from said reservoir and upon receipt of said fluid to undergo a change;
- and
- a pressure sensitive barrier between said reservoir and said fluid responsive region adapted to prevent flow of fluid from said reservoir to said fluid responsive region if the pressure drop across said pressure sensitive barrier is below a first pressure difference and to permit flow of fluid from said reservoir to said fluid responsive region if the pressure drop across said pressure sensitive barrier exceeds said first pressure difference;
- wherein said pressure sensitive barrier is configured to permit flow of fluid from said reservoir at least in part due to at least one of angular acceleration, angular deceleration or centripetal acceleration of the data storage device.
