摘要： A head stack assembly for a disk drive. The head stack assembly includes an actuator defining an axis of rotation. The actuator includes an actuator arm defining a longitudinal axis orthogonal to the axis of rotation. The actuator includes an actuator body formed of overmolded plastic. The actuator includes first and second locking pins extending from the actuator body orthogonal to the axis of rotation. The flex cable includes a first opening engaged with the first locking pin in a direction generally parallel to the longitudinal axis for retaining the flex cable. The flex cable includes a second opening engaged with the second locking pin in a direction generally parallel to the axis of rotation for retaining the flex cable.

摘要： A disk drive includes a voice coil motor (VCM) having a narrow coil angle and a magnet magnetized with two or three pole pairs. The VCM magnet may define first, second and third sections, the second section being magnetically polarized in an axial direction that is opposite to that of the first and third sections. The first radial leg of the VCM coil faces the second section and the second radial leg faces the third section when the head is positioned at a non-operational position. The first radial leg faces the first section and the second radial leg faces the second section when the head is reading and/or writing to the data portion of the disk. Alternatively, the VCM magnet defines first and second sections that are magnetized in opposite axial directions. The first and second radial legs of the VCM coil respectively face the first and the second sections when the head is positioned over the data portion of the disk and only the first radial leg faces the second section when the head is at a non-operational position.

摘要： A static bi-stable mechanical latch comprises a latch member pivotally mounted to a frame and rotatable between an opened-position stop and a closed-position stop. The latch member includes a first arm having a hooked end and a magnetic mass mounted thereon, and a second arm having a latch coil and a soft magnetic mass mounted thereon. The second arm is also provided with a tang or bump. The actuator is provided with an angular protuberance and a tip which is captured by the hooked end of the latch member when the actuator arm is positioned so that the head is in the landing zone and the latch member is in the closed position. The pivot point of the latch member is positioned so the angular protuberance of the actuator arm engages the tang or bump when the actuator is moving towards the landing zone and is in a preselected position close to or in the landing zone. A magnet assembly comprising at least one mounted permanent magnet is positioned with respect to the actuator coil so as to allow control of the actuator position by controlling electric current passing through the actuator coil and with respect to the latch coil so as to apply a torque to rotate the latch member by passing current through the latch coil. The magnet assembly is configured and positioned such that its magnetic field force attracts both magnetic masses. Depending on the rotational position of the latch member, one force prevails over the other.
