Abstract:
In a data storage system including a rigid disk drive data storage device including at least one disk rotated by a spindle motor, at least one transducer head that flies over at least one respective confronting disk surface that includes a highly polished data storage surface portion and a security means, for preventing unauthorized access to data, that must be satisfied to enable access to stored data, a data protection system comprisingsensing means for sensing consecutive unsuccessful attempts to satisfy said security means, anddisabling means invoked by said sensing means and operable to disable said disk drive by landing said at least on transducer head on said respective at least one disk highly polished data storage surface portion, whereby the at least one transducer head sticks to the respective disk polished surface with an adhesive force that requires a greater starting torque than can be supplied by said spindle motor at startup.
