Title: The Innovations of David M Chick
Introduction
David M Chick is a notable inventor based in Aldershot, GB. He has made significant contributions to the field of data storage technology, holding a total of 2 patents. His work focuses on improving the efficiency and accuracy of magnetic disc storage devices.
Latest Patents
David's latest patents include a "Magnetic disc storage device with track centering correction." This invention involves a magnetic disc data storage device that utilizes exchangeable magnetic discs for recording data signals. A track containing reference signals is provided, and a read-write head is moved to the reference track. As the disc rotates, the position of the head relative to the axis of rotation is sampled. Any errors in the position of the reference signals due to eccentricity of the track are stored and used during subsequent accesses of data tracks to modify the head position, ensuring that the head follows a track with a predetermined spatial relationship to the reference track.
Another significant patent is for "Magnetic disc storage devices having compensation for dimensional changes." In this invention, a reference track is provided on the disc, and during interruptions in data transfer, the read-write head is moved to the reference track. The error in its expected position, due to dimensional changes in the disc or misalignment of the head, is measured. In subsequent data track access, the position of the head is corrected by the measured error, ensuring correct alignment with the selected data track. Measurement of the error is carried out more frequently when the error is changing rapidly.
