ABSTRACT:
A magnetic tape driving apparatus includes: a stationary magnetic head capable of recording and reproducing digital signals simultanouesly on multichannel tracks; tape guide members for drawing out a magnetic tape wound on a pair of tape supply/take-up reels contained in a cassette, contacting the magnetic tape with the stationary magnetic head, and guiding running of the magnetic tape; and a constant speed driving mechanism for holding the magnetic tape and making it run at a constant speed by capstans and pinch rollers provided on both of tape feed/take-up sides of the stationary magnetic head. The stationary magnetic head and the tape guide members having level regulators for regulating running positions of upper and lower edges of the magnetic tape, to regulate the level of running of the tape with high precision. The rotating speeds of the capstans on both of the tape feed/take-up sides are regulated, whereby the tension of the tape is maintained at a desired prescribed value, to ensure a stable running of the tape.
