Magnetic recording and reproducing apparatus which prevents erasing during tape loading

Abstract

Abstract IN A MAGNETIC RECORDING AND REPRODUCING APPARATUS WITH AN AUTOMATIC TAPE LOADING DEVICE FOR DRAWING A MAGNETIC TAPE FROM BETWEEN REELS ON WHICH IT IS WOUND, FOR EXAMPLE, IN A CASSETTE OR CARTRIDGE, AND WRAPPING OR LOADING THE WITHDRAWN TAPE ABOUT A GUIDE DRUM HAVING AT LEAST ONE ROTARY MAGNETIC HEAD ASSOCIATED THEREWITH TO SCAN THE TAPE ON THE DRUM DURING RECORDING AND REPRODUCING APPARATUS, AND IN WHICH AN ERASING HEAD IS PROVIDED TO ERASE SIGNALS ON THE TAPE PRIOR TO THE SCANNING THEREOF BY THE ROTARY HEAD DURING RECORDING OPERATIONS, A SINGLE MANUALLY ACTUABLE RECORDING CONTROL IS PROVIDED TO INITIATE THE RECORDING OPERATION BY FIRST CAUSING OPERATION OF THE TAPE LOADING DEVICE, AND THE COMPLETION OF THE TAPE LOADING OPERATION IS DETECTED, FOR EXAMPLE, BY AUTOMATIC ACTUATION OF A SWITCH IN RESPONSE THERETO, TO ONLY THEN PERMIT ENERGIZATION OF THE ERASING HEAD, AND PREFERABLY ALSO OF A RECORDING CIRCUIT, FOR AVOIDING ERASURE FROM THE TAPE OF SIGNALS WHICH IT IS DESIRED TO RETAIN OR THE UNDESIRED RECORDING ON THE TAPE OF THE ERASING SIGNAL IN THE FORM OF NOISE.
