摘要： A method of inhibiting inadvertent and unauthorized writing and reading of information to and from a storage medium comprises the steps of (a) writing a first code in a predetermined location on the storage medium, the first code being indicative of a first protection mode of the storage medium; (b) receiving a command to change the protection mode of the storage medium from the first protection mode to a second protection mode; and, in response to the command, (c) writing in the predetermined location on the storage medium, in place of the first code, a second code indicative of the second protection mode. A protection mode can inhibit writing to the storage medium, both writing and reading to and from the medium, or neither. Changing of protection modes can also be password protected.

摘要： A disk drive power manager that compares energy usage with a predetermined profile to select one of several reduced-power operating modes. An energy usage register is updated at regular intervals according to the energy used during each time interval. An attenuated average energy usage value is obtained by attenuating the energy usage measures over time and integrating the results. The average energy level is compared with several predetermined energy threshold profiles to select a full- or reduced-power operating mode. Operating mode selection automatically adapts to the usage pattern to optimally balance power consumption with operational accessibility.

摘要： A capacitive variation sensor includes one or more elements providing inductive reactance in the form of thin film coils. This enables a capacitive variation sensor to be integrated on a substrate along with a thin film magnetic read/write head. One element of the capacitive variation sensor is a sensing electrode, and in some embodiments of the invention a dedicated sense electrode can be eliminated by employing the pole tips of the thin film magnetic read/write head as the sense electrode.

摘要： A module carrying microcircuit LSI chips includes stacks of parallel ceramic sheets carrying thin capacitor plates laminated in a ceramic structure in which the capacitor plates either serve (1) as the power distribution conductors known as power planes or (2) are connected to power conducting vias which pass through the capacitor plates. Those vias connect to the appropriate capacitor plates electrically, thereby locating the capacitance required as close as possible to the solder bonds between the chips and the carrier. Stacks of laminated ceramic capacitors serving as power planes can be inserted into slots in laminated ceramic sheets providing the first arrangement above. Signal vias are provided about the periphery of the power planes. A highly parallel distribution of current is provided by means of horizontal power conducting straps which reduce voltage fluctuations, electrical resistance, and current per via.

摘要： Using a sonic delay line approach, the distance of a point from the ends of a wire is measured by the time required for an acoustic pulse to move along a wire. A magnetostrictive wire extends between its endpoints with several magnetic pickup coils connected in series located at each end of the wire which are adapted to pick up an encoded train of magnetoacoustic signals. A position signalling electromagnetic drive head can be moved along the coil to any desired position. The head can be pulsed electrically to produce an appropriate sequence of acoustic pulses in the magnetostrictive wire. When those pulses are received by an appropriate sequence of coils connected in series which are properly connected (plus and minus), a large pulse is produced at one time position of the waves as they pass through the sequence of coils. Otherwise, a small signal is produced while the pulses pass by. The drive head comprises a Barker sequence coil which produces 3, 7, or 11 pulses in a Barker sequence, which gives a maximum positive autocorrelation, with an output of less than zero for all other positions of the sequence of pulses as they pass through a series of coils. This large output signal is used in conjunction with a timer to provide position measurement. By placing detectors at both ends of the wire, it is possible to provide self-calibration against thermal and other drifts in accuracy and to provide immediate warning of noisy or invalid readings.
