Title: The Innovations of Edward E. Griffin
Introduction
Edward E. Griffin is an accomplished inventor based in Edina, MN, with a notable portfolio that includes two patents. His work primarily focuses on advancements in technology, particularly in the realm of magnetic tape recording systems.
Latest Patents
One of Edward E. Griffin's latest patents is the Magnetic Tape Recording Head Cleaning Apparatus. This innovative device employs dry cleaning techniques to clean the read/write head of contact transducing types found in computer data backup tape drive systems. The apparatus features a housing that encloses a supply reel holding cleaning tape, a takeup reel for used or soiled tape, and a gear train that transmits rotary power at a reduced speed from an external power source, such as the tape drive capstan, to the takeup reel. The gear train consists of multiple gears that create a gear reduction system, allowing the cleaning tape to be driven past the head at an effective cleaning speed significantly lower than the normal read/write speed of the tape drive. Additionally, the apparatus includes a movable shutter mechanism that blocks one of the light paths between a light emitter and a light sensor, providing a unique signal to the tape drive. This shutter mechanism is activated upon insertion into the tape drive, ensuring that the cleaning cycle operates for the preferred time period set by the tape drive manufacturer.
