Abstract:
1. A tape head read/write module having a composite air bearing surface, the module comprising: a substrate having an air bearing surface, a front, a back, and a chip receiving slot, wherein the chip receiving slot has a front at the front of the substrate, a back at the back of the substrate, a first side, a second side, and a bonding surface, and wherein the air bearing surface of the substrate has a first portion adjoining the first side of the chip receiving slot, and a second portion adjoining the second side of the chip receiving slot; and a chip that has an air bearing surface, a bottom surface, a front, a back, and active elements, wherein the active elements are located proximate to the front of the chip, and wherein the chip is inserted in the chip receiving slot in the substrate with the air bearing surface of the chip substantially aligned with the air bearing surface of the substrate; wherein the chip receiving slot in the substrate has a first side trough proximate to the first side of the chip receiving slot and a second side trough proximate to the second side of the chip receiving slot; and an adhesive layer attached to the bonding surface of the chip receiving slot and the bottom surface of the chip, wherein the adhesive layer fills at least a portion of the first side trough and the second side trough.
