Latest Patents

Johannes holds a patent for an invention titled "Automatic disk change detection without causing head movement." This patent describes a method and apparatus for detecting diskette changes by generating a step pulse signal using the CPU. This signal is sent to the step pulse line of the disk drive, allowing the CPU to issue a step pulse directly without relying on the floppy disk controller. By positioning the head in the outermost cylinder and issuing a step pulse when the direction signal indicates outward movement, the door-open status signal can be updated without causing head movement. This innovation prevents excessive head movement, drive spinning, and unnecessary noise, while also conserving CPU resources.
