摘要： A signal amplitude comparator which includes a first input that receives an input signal and generates an output signal that is a non-linear function of the input signal, and a second input circuit that receives a reference input signal and generates a second output signal that generally tracks process, temperature and supply variation. The signal amplitude comparator also includes an amplifier, a filter and a comparator. The amplifier amplifies a signal difference between the first and second output signals and outputs a train of pulses if a peak of the input signal exceeds the reference input signal. A second reference signal is applied to the comparator which generates an output which indicates whether the input signal exceeds a pre-determined threshold value. The signal amplitude comparator also includes a pair of input amplifiers which receive and translate the input and reference input signals to levels suitable for the input circuits.

摘要： A magnetic tape drive having a motor with a magnetically shielded cavity or hole in one cover of the motor providing additional room for movement of a magnetic head. The cavity eliminates a mechanical interference problem, enabling direct drive of a roller (puck) combined with short overall drive height. In motors having an internal stator, some of the stator poles are eliminated and a magnetically shielded cavity is provided in the area where the stator poles are eliminated. In motors having an external stator, no stator modification is required and a shielded cavity provides access into an open area of the rotor. In addition, for motors having an external stator and sufficient magnetic shielding, a simple hole in one cover of the motor may be sufficient rather than a magnetically shielded cavity.

摘要： The present inventions are related to systems and methods for pre-equalizer noise suppression in a data processing system. As an example, a data processing system is discussed that includes: a sample averaging circuit, a selector circuit, an equalizer circuit, and a mark detector circuit. The sample averaging circuit is operable to average corresponding data samples from at least a first read of a codeword and a second read of the codeword to yield an averaged output based at least in part on a framing signal. The selector circuit is operable to select one of the averaged output and the first read of the codeword as a selected output. The equalizer circuit is operable to equalize the selected output to yield an equalized output, and the mark detector circuit is operable to identify a location mark in the equalized output to yield the framing signal.

摘要： An integrated circuit having input output buffers, where the integrated circuit is powered by at least a core power supply and an input output power supply. A level shifter receives an active low signal that indicates that the core power supply has powered down. The level shifter then outputs a known state upon receipt of the active low signal. A control circuit receives the known state form the level shifter, and then tristates the input output buffers upon receipt of the known state.

摘要： A system and method for reducing non-repeatable positioning errors. Non-repeatable positioning errors caused by the effects stiction and backlash in the mechanical system are reduced by "shaking" or vibrating the positioning system in a controlled manner. After the system input is set to the desired value, the positioning system is "shaken" by inputting a series of offsets that oscillate around the desired location and gradually decrease in amplitude, eventually reaching zero. In a specific embodiment, a lead screw is threaded through a follower nut which is connected to a magnetic tape read/write head. The lead screw is rotated by a mechanical transmission which provides gear reduction from a computer controlled stepper motor. The tape head's non-repeatable positioning error is reduced by alternately stepping the stepper motor in opposite directions a specified number of steps and periodically reducing the specified number of steps until zero is eventually reached.

摘要： A tape guide for a digital tape mini-cartridge providing decreased tape wander in a direction transverse to the intended path. The guide provides an increased area of tape having increased transverse stiffness without interfering with an adjacent drive wheel. In one embodiment, the guide is cylindrical and has a cylindrical cut-out to provide clearance for an adjacent cylindrical drive wheel. Preferably, the guide has top and bottom flanges. If a top flange of the guide is present, the cut-out continues through the top flange of the guide. The top flange of the guide may be relatively thin to fit below a top flange of the adjacent drive wheel. Alternatively, the top flange of the guide may have a larger cut-out to avoid interference with the top flange.
