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.
Claims11
A method of configuring a disk drive for use with a rotation-sensitive disk, comprising:
- providing read head position instructions, including commands for controlling the position of a read head with respect to a disk received in the disk drive;
- providing motor control instructions including commands for controlling rotational movement of a disk received in the disk drive during reading;
- providing read instructions for managing reading of data from the disk with a sensor;
- and
- providing data degradation instructions for controlling duration and speed of rotation of the disk at levels sufficient to induce degradation in the rotation-sensitive disk,
- wherein one or more of said read head position instructions, said motor control instructions, said read instructions and said data degradation instructions are provided in the form of software, hardware or firmware.
