摘要： An improved magnetic head assembly is provided by the invention, wherein the upper head device is biased toward the lower head device by a bias means while the lowest position of the upper head device where it comes closest to the lower head device is strictly defined by a stopper means whose position is changeable so that a correct gap is realized between the two head devices. Consequently, even if the upper head device is subjected to adjustment operations to align the upper head to a track while it is under pressure, the upper head device is completely free from any displacement after the adjustment operations and variations of in tracking due to variations in the pressure applied to the magnetic disc by the upper head device.

摘要： A motor and a recording and/or reproducing apparatus using the motor. The motor includes a rotational member, a fixed member, a stopper member and a set of balls. The rotational member is formed by bending a first plate, and includes a first V-shaped bearing guide groove and central rotational shaft having a hole formed therein. The fixed member is formed with a second V-shaped bearing guide groove and bent portions which are used to attach the fixed member to a chassis. The balls are mounted in the first and second V-shaped bearing guide grooves and allow the rotational member to rotate relative to the fixed member. The stopper member is inserted through a central opening in the fixed member and is received in the hole formed in the rotational shaft, thereby connecting the rotational member to the fixed member so that the motor can be transported as a unit without separating.
