ABSTRACT:
A data tape cartridge is formed on a baseplate of polymeric material which supports mounting pins and tape guides thereon for supporting tape components in rigid and dimensionally-stable manner using integrally formed bosses to support the mounting pins and guides. Additional stability against flexure is achieved using a matrix pattern of integrally-formed webs or ribs and sidewalls in the baseplate and by attaching a top plate substantially about the entire perimeter of the sidewalls. Lateral forces exerted against rotatable components on the mounting pins are transferred to the baseplate and top plate by the mounting pins that are supported in both plates. A midguide support is integrally formed in the baseplate to support a guide pin at critical location adjacent the location along the tape path in the cartridge at which a tape transducer interacts with tape. Methods of assembly include inserting mounting pins and tape guides into the baseplate while the material of the baseplate about the mounting pins is plasticized, and also include assembling the components of the cartridge in upside-down orientation for transfer to aligned pins and guides in the baseplate.
