Latest Patents

One of Shidler's latest patents is a precision measurement and positioning system for disk storage systems. This invention utilizes a small-sized, low-cost, high-accuracy semiconductor laser interferometer to position the transducer in a disk storage system. The light is reflected back over the path to be measured and directly back into the semiconductor laser, causing the power present in the laser to vary. Unexpectedly, the output of the photosensor associated with the laser exhibits an asymmetric, sawtooth waveform. Another significant patent is related to magnetic disk-control track read through an envelope. This invention records control information for a flexible magnetic disk storage assembly on the periphery of the disk in a region not used for recording data. The control information is read through the protective cover or envelope enclosing the disk by means of a magnetic transducer, such as a four-track audio cassette head. By recording index and sector pulses as part of the control information, hard sectoring can be achieved inexpensively and accurately.
