ONE PIECE CORE AND PLATFORM FOR ENDLESS TAPE CARTRIDGES

摘要

This invention relates to an integrally molded core and platform for an endless array of magnetic tape for use in cartridges. The core is integrally connected to the platform in a one-piece construction. The upper exterior portion of the core is defined by two oppositely facing radii having a common tangent in order to minimize tape drag and hang-up or catching of the tape as it releases from the inside of the spool to be transported to the transducer head.
