ABSTRACT:
A head stack assembly comb (154) for maintaining the heads (44) of a head stack assembly (26) in spaced relation is disclosed. The head stack assembly comb (154) includes a comb body (158) and a latch (218). The comb body (158) engages an upper surface of an uppermost actuator arm (30a) in the head stack assembly (26). The latch (218) engages a lower surface of this same actuator arm (30a). When installing the comb (154), the comb (154) is pivoted relative to the head stack assembly (26). This brings the latch (218) into engagement with the noted actuator arm (30a) and causes the latch (218) to pivot in a first direction against a spring (214), and then in the opposite direction by the action of the spring (214) on the latch (218) to engage the latch (218) with the lower surface of the noted actuator arm (30a).
