Title: Innovations of David P Gregg in Optical Technology
Introduction
David P Gregg, an esteemed inventor located in Culver City, CA, has made significant contributions to the field of optical technology through his innovative inventions. With a remarkable portfolio holding 15 patents, Gregg's work primarily focuses on enhancing optical tape mechanisms, underscoring his role as a leader in this niche area of technology.
Latest Patents
One of David P Gregg's latest patents is an "Optical tape cartridge having improved tape movement mechanism." This inventive design involves an optical tape cartridge engineered for use with an optical tape player, which supplies a substantial voltage to facilitate enhanced tape operation. The cartridge consists of a sealed housing with two tape reels, allowing smooth rotation in either direction. The optical tape retains an important feature of a conductive layer that extends the length of the tape and is grounded at least at one end. This innovation also includes a sealed window in the housing for optical reading, alongside a conductive guide that assists in maintaining the proper distance of the tape from the window through electrostatic attraction.
Another notable patent from Gregg is an "Optical tape duplicator," which allows for the efficient duplication of recorded optical tape via continuous contact recording. This duplicator design holds a master tape in contact with an optical tape, which is then exposed to a beam of radiant energy. The energy passes through the transmissive portions of the master tape, enabling the recording of information onto the optical tape. This invention exemplifies his commitment to advancing optical tape technology for various practical applications.
