Abstract

PURPOSE: To obtain tape drive information of high precision by obtaining the information on magnetic tape drive from a reproduced control signal and information obtained from a body of revolution turning as a magnetic tape runs.
CONSTITUTION: The rotary disk 4, video heads 1 and 2, rotary-phase detecting magnet 3 are fitted and corresponding to magnet 3, rotary-phase detector 5 is arranged on the fixed-part side. Rotary disk 4 turns as a high speed by DC motor 6 as shown by arrow 25. The output signal of frequency dynamo 7 fitted to motor 6, that of rotary-phase detector 5 and that of reference oscillator 10 are supplied to drum servo circuit 8 and then supplied to DC motor 6 by way of a driving circuit. Magnetic tape 23 is driven by capstan 11, a pinch roller and DC motor 15 as shown by arrow 24 and slit-attached disk 19 and rotary phase detector 20 detect the rotary phase of capstan 11, so that tape drive information can be obtained.
