PURPOSE:To ensure a tracking action with a high precision, by supporting the center part of a magnetic head supporting member with an elastic member having a damper property. CONSTITUTION:Magnetic heads 11a and 11b are stuck to brackets 12a and 12b, and these brackets are fixed to both the ends of a head attachment body 13 with screws 14a and 14b respectively. The body 13 is fitted to a projected flange 15c of a rotary member 15 via a center hole 13a of the body 13 and then fixed onto the upper surface of the member 15 with screws 16a and 16b. The member 15 has yoke parts 15a and 15b formed at both-end sides. A seesaw plate 20 is supported by a pair of rubber blocks 22a and 22b in a slightly floating state by a fixed seesaw base 21 and while being fitted with play to a rotary shaft 5. The base 21 is fixed onto a base plate 7 with screws 23a-23d. |
