An IBM Executary unit 1 is modified for student instruction. Unit 1 has an associated microphone 2 with control switches 3 and 4 and dictate bar 5. Switch 3 is operated to effect instructions in an index slip 6. Switch 4 is moved to the upper position for recording, to the center position for listening, and to the lower position for review purposes. During recording, the machine is started and stopped by depression of dictate bar 5.

The housing of unit l is partially cut away to show the details of the instruction area. Mounted in the top of the housing is a rectangular window 7 with an associated sliding lens 8. Window 7 and lens 8 are shown in cross-section in the lower drawing. Magnetic belt 9 has alternate prerecorded areas (shaded) and unrecorded areas (unshaded). Belt 9 is mounted in mandrels 10 and 11 in order to be driven underneath window 7.

As an example, belt 9 has a foreign language phrase visibly printed in each prerecorded area along with the corresponding aural foreign language version or aural English translation. The English translation is also printed in the associated unrecorded area. Lens 8 is pivotally attached at 12 to sound head
