    摘要: A method and apparatus is provided for aligning and press-fitting connector terminals into a substrate. The terminals are initially supported together by a bandolier strip, and an alignment tool aligns the terminals with apertures in the substrate to which the terminals will be press-fitted. A pressing tool engages the shanks of the terminals to fold the bandolier away from the terminals and thereafter press the terminals into the apertures.

    摘要: A read signal processing circuit for a magnetic storage disk. The processing circuit used to accomodate intersymbol inference and base line noise problems of a magnetic recording code having minimum to maximum flux reversal time span ratio of 3-10. The circuit receives an amplified analog read signal and outputs a binary reconstruction of the original encoded write signal.

    摘要: Electronic circuitry for improving the speed and accuracy of shifting the magnetic heads of a disk memory from one to another track cylinder. Head velocity is measured with great accuracy by measuring the servo head transit time between adjacent tracks of the servo disk. A microprocessor controller in conjunction with preferred velocity profile data stored in a read only memory provides a control signal to the linear motor control causing the head arm velocity to follow the preferred velocity profile with excellent precision.

    摘要: A cateye-signal intercept detector for aligning a read-write head above a computer data storage disk. The detector used in conjunction with a standard disk having two adjacent cateye-type head alignment tracks thereon. The subject invention automates the detection of each intercept in the cateye-signal so that associated processing equipment responsive to the output signal produced can measure the read-write head disk alignment automatically.

    摘要: A disk memory drive mechanism for accepting a disk memory module from a front-located port and conveying it to a seated position on the spindle, and for detaching it from the spindle and conveying it back to the loading port for removal. The module-conveying mechanism is activated by opening and closing the door for the loading port which seals it from the ambient air.

    摘要: A dual loop phase locked oscillator system comprises a pair of phase locked oscillators coupled with priority logic gates for selectively operating each oscillator. During a lock-to-data mode, the logic gates are operated so that one of the oscillators is operated by the input data to lock to the data rate, while the other oscillator is operated by the output of the first oscillator to also lock to the data rate. During a normal mode, or coasting mode (when no data is present), each oscillator operates off the output of the other to thereby maintain oscillation at the data rate. Thus, the oscillators are selectively operated in tandem or in parallel.

    摘要: A balancing apparatus for balancing a high precision magnetic disk drive includes a plate having a circular aperture in which three mounting surfaces grip a precision mounting ring on the disk pack to be balanced. The plate is mounted on a pivoting platform so that the pack can be lowered into the aperture, gripped by the mounting surfaces and then flipped into a horizontal position for balancing such that an operator has access to the disk pack to add balancing weights through the circular aperture.
