Abstract

A dictating machine of the type having a relatively short, wide, magnetic recording belt 2 is modified to provide an audio response unit for a teaching machine. The conventional dictating apparatus 5 is mounted on a housing 3 that contains a stepping motor and an indexing mechanism for the record and playback head of the dictation unit. The stepping motor advances the tape head in increments so that the recording is on short parallel tracks instead of the conventional continuous spiral along the belt. A mark on the tape provides a reference for a starting line for each track. The stepping motor is given an address by a processor 4.

Teaching Apparatus Having Audio Responses Recorded on Parallel Magnetic Tracks

A dictating machine of the type having a relatively short, wide, magnetic recording belt 2 is modified to provide an audio response unit for a teaching machine. The conventional dictating apparatus 5 is mounted on a housing 3 that contains a stepping motor and an indexing mechanism for the record and playback head of the dictation unit. The stepping motor advances the tape head in increments so that the recording is on short parallel tracks instead of the conventional continuous spiral along the belt. A mark on the tape provides a reference for a starting line for each track. The stepping motor is given an address by a processor 4. The stepping motor rapidly scans the head across the tape to the selected track, and the conventional belt drive mechanism brings the belt to the reference position where a selected response begins.

The unit of the drawing is to be used with a program that runs on processor
4. The student has an input device, such as a display 7 with a light pen or a keyboard. The processor holds a program for responding to this input from the student during a lesson.

An instructor who is preparing a lesson that is to be used with this apparatus uses unit 5 as a normal dictation unit. The instructor dictates into the microphone 6 to record responses and alternate responses that can be selected during a lesson. The address of the track for a particular response is entered int...
