Transport comb for head stack assembly

摘要

An HSA transport comb includes an alignment pin extending from the comb body into a tooling hole of the actuator arm, and a separator finger in contact with a suspension assembly of an HGA with the transport comb in a second angular orientation with respect to the actuator arm, but not in a first angular orientation. The transport comb includes a restraining tower extending into a mass-reduction opening of the actuator arm. The restraining tower includes a first lobe that fits within the mass-reduction opening with the transport comb in the first angular orientation, but not with the transport comb in the second angular orientation. The restraining tower also includes a first neck that fits within the mass-reduction opening with the transport comb in either angular orientation, and has a neck height that is greater than the actuator arm thickness.

1. A transport comb for a head stack assembly (HSA) that includes a head gimbal assembly (HGA), the transport comb comprising:
a comb body; an alignment pin extending from the comb body; at least one separator finger extending from the comb body; and a restraining tower, extending from the comb body, for preventing the transport comb from being inserted into the HSA unless the at least one separator finger is angularly displaced away from the HGA wherein the at least one separator finger is in contact with a suspension assembly of the HGA if the transport comb is in a second angular orientation with respect to an actuator arm of the HSA, and the separator finger is not in contact with the suspension assembly of the HGA if the transport comb is in a first angular orientation with respect to the actuator arm, and wherein the restraining tower comprises:
a first lobe that fits within a mass-reduction opening of the actuator arm if the transport comb is in the first angular orientation, and the first lobe does not fit within the mass-reduction opening if the transport comb is in the second angular orientation; anda first neck that fits within the mass-reduction opening if the transport comb is in the first or second angular orientations, the first neck having a neck height that is greater than an actuator arm thickness.
