Publication number: 20080304185Abstract: A method of manufacturing a drum assembly associated with a digital betacam video tape machine is disclosed. The method includes providing a helical scan drum assembly having a stationary upper drum, a stationary lower drum and a plurality of rotating read/write heads disposed between the stationary upper and lower drums. The rotating read/write heads reading and writing digital information to and from a tape. The method further includes inserting air grooves in the outer peripheral surface of the upper drum. The air grooves are configured to reduce sticktion between the tape and the outer peripheral surface of the upper drum when the tape is moved around the outer peripheral surface of the upper drum. The method additional includes mounting an adjustable band to the outer peripheral surface of the lower drum. The adjustable band is configured to guide the tape around the drum assembly in accordance with helical scans when the tape is moved around the outer peripheral surface of the upper drum.Type: ApplicationFiled: June 6, 2007Publication date: December 11, 2008Inventors: George Athanasiou, Constantine Athanasiou
