ABSTRACT:
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.
