摘要 A magnetic tape unit comprising a head component having a rotatable drum provided with a magnetic head, a guide plate having a tape guide mechanism for leading a magnetic tape into contact with the head component, a supporting base for supporting the head component with the rotation surface of the magnetic head inclined at predetermined angle against the guide plate, the thermal coefficient of expansion thereof being different from that of the guide plate, and mounting means for fitting the supporting base to the guide plate and for absorbing the difference in the degree of expansion and contraction therebetween appeared in a direction in parallel with the surface of the guide plate due to the difference of the thermal coefficient of expansion therebetween. As described above, by use of the magnetic tape unit according to the present invention, the expanded portion of the supporting base is absorbed due to the fact that the thermal coefficient thereof is greater than that of the guide plate, whereby the tape inclination angle formed between the rotation surface of the magnetic head and the guide plate is not easily affected by any temperature fluctuation, so that the predetermined angle becomes invariable.
