The present disclosure is generally related to a tape head assembly narrower than the width of a tape, wherein the tape head assembly comprises one or more heads, wherein each of the one or more heads comprise a curved surface comprising a first beveled wing, a second beveled wing, and a flat-lapped surface disposed between the first beveled wing and the second beveled wing. The first beveled wing and the second beveled wing each comprise outer corners recessed from a top surface of the flat-lapped surface such that there is no interaction between the outer corners of the beveled wings and the tape.

Aspects of the present disclosure generally relate to a base and related methods for write and read heads. In one example, the base and related methods are used as part of a magnetic storage device, for example a magnetic media drive such as a hard disk drive (HDD) or a magnetic tape drive (e.g., a tape embedded drive). The base includes one or more base bodies formed of a ceramic material. Each base body includes an inward surface, an outward surface opposing the inward surface, a lower surface, and an angled upper surface disposed above the lower surface. Each base body includes a vertical opening extending between the upper surface and the lower surface. In one example, two base bodies are bonded together. In one example, the two base bodies combine to form a single base body of the base that is monolithic and unitary.

Embodiments disclosed herein generally relate to a method for forming a HAMR head. The method includes depositing a drop-on-demand mask on a portion of a surface of a slider using a drop-on-demand tool. The surface of the slider includes at least a portion of an NFT. A first protective layer is deposited over a remaining portion of the surface of the slider and over the drop-on-demand mask. The drop-on-demand mask and a portion of the first protective layer disposed on the drop-on-demand mask are removed, exposing at least the portion of the NFT. A second protective layer is deposited on the first protective layer and at least the exposed portion of the NFT. By using the drop-on-demand tool to deposit the drop-on-demand mask, the alignment between the drop-on-demand mask and the portion of the NFT is less stringent, and the drop-on-demand mask can be easily removed using a wiping tool.
