Patent ID: 7916592

Claim:
A system comprising: electrical circuitry including a microprocessor; an input device operably coupled to said electrical circuitry; an output device operably coupled to said electrical circuitry; a data storage device configured for rotating access operably coupled to said electrical circuitry, said data storage device including: a substrate; a degradation-sensitive data storage medium on said substrate; a fluid reservoir containing an electrically conductive fluid; a rotation activatable fluid release mechanism for controlling release of said electrically conductive fluid from said reservoir to produce degradation of said data storage medium; a fluid receptacle adapted to receive said electrically conductive fluid released from said reservoir; a first electrical contact on a first side of said fluid receptacle; and a second electrical contact on a second side of said fluid receptacle, said first electrical contact and said second electrical contact disposed so that, upon receipt of said electrically conductive fluid by said fluid receptacle from said reservoir, an electrical connection will be formed between said first electrical contact and said second electrical contact.
