摘要： A hard disk drive with a voice coil motor coupled to a head. The head moves relative to a disk. The voice coil motor receives a biasing voltage and has a back emf voltage. A test circuit is coupled to the voice coil motor to determine the back emf voltage. The back emf voltage can be used to analyze low frequency vibration in the disk drive. The test circuit can be constructed so that the back emf voltage is proportional to a pair of test resistors and/or a pair of test inductors. The biasing voltage allows the back emf voltage to be measured and analyzed while the head is at any location from the ID to the OD of the disk.

The head stack assembly includes a body portion defining a through bore that defines a pivot axis; an actuator arm cantilevered from the body portion and a head gimbal assembly coupled to the actuator arm. A coil portion is cantilevered from the body portion in an opposite direction from the actuator arm. The coil portion defines first and second actuator fork members and includes a coil supported by the first and second actuator fork members. A bobbin is configured to stiffen the coil portion, and is attached to an inner periphery of the coil. The bobbin may define a first truss and a second truss that crosses the first truss. An adhesive is disposed between the bobbin and the wound coil.
