MAGNETIC RECORDING AND REPRODUCING DEVICE AND ROTARY MAGNETIC HEAD DEVICE USED FOR THIS DEVICE

摘要

PROBLEM TO BE SOLVED: To facilitate the addition of an impedance roller. SOLUTION: A motor stator 12b is so mounted so that its square part is directed in the direction averting the position of an impedance roller 19 to make the attachment and detachment of the impedance roller 19 alone possible. Since the impedance roller 19 is mountable after the traveling state of a tape was adjusted, the assembling stage is rationalized. The effect is easily enhanced by increasing the size of an inertia body 19b.
