Title:
VIDEO SIGNAL REPRODUCER
Document Type and Number:
Japanese Patent JPS59157804
Kind Code:
A
Abstract:

PURPOSE: To obtain a compact and lightweight video signal reproducer by winding a magnetic tape around a tape guide drum within an angle range of 300° and providing rotary heads of different extending directions of gaps to have alternating rubs to the magnetic tape.

CONSTITUTION: A magnetic tape 2 is wound around a tape guide drum 1 within an angle range of 300°, and six reproduction rotary heads 4A, 7A and 9A as well as 6B, 8B and 10B are set with 60° angle spaces and have the same extending directions of gaps every second one. A revolution control part revolves these six heads at 300°/360° times as much as the field frequency, and a switching circuit 57 extracts the reproduction outputs of these heads successively for every field. In such a constitution, the diameter of the drum 1 is decreased to realize a compact and lightweight recording/reproducing device for video signal.
