The disk in a computer’s magnetic hard drive spins about its center spindle while the recording head C reads and writes data (Figure P8.19). The head is positioned above a specific data track by the arm, which pivots about its bearing at B. As the actuator motor A turns through a limited angle of rotation, its 6-mm-radius pinion rotates along the arc-shaped segment, which has a radius of 52 mm about B. If the actuator motor turns at 3000 deg/s over a small range of motion during a track-to-track seek operation, calculate the speed of the read/write head.
