Abstract

A tape cartridge or magazine and reading apparatus therefore are provided wherein tape in the cartridge may be driven past a plurality of transducers supported by a mount for the cartridge when the cartridge is predeterminately located on said mount. The cartridge contains an opening exposing a length of the recording tape to a bank of transducers. In one form, the transducers comprise a plurality of switches arranged in parallel circuits which are made and broken when perforations in the tape are sensed by the switches. In another form, recordings on the tape are sensed by respective transducers disposed off the tape as it is driven therepast. Suitable tape tensioning means associated with the mount is operative after properly mounting the cartridge, to engage and predeterminately provide tension in the tape driven past the bank of transducers. In another form of the invention recording is effected on the tape and the cartridge by a bank of transducers operative to punch holes in the tape as it is driven therepast.
