Optical sensor to recording head alignment
First Claim
1. A recording head in a read/write assembly of a magnetic recording tape system comprises:
- a plurality of recording channels fabricated on a wafer; and
an alignment target affixed to the wafer between a first read-write element of a recording channel and a second readwrite element of the recording channel, the alignment target fabricated to produce an optical reflectance signal, wherein the alignment target comprises a plurality of etched alignment grooves, each of the grooves spaced apart from each other and arranged parallel to a direction of magnetic tape travel.

Abstract
A technique of positioning a recording head relative to an optical servo system in a magnetic recording tape system read/write assembly is described. The technique includes positioning an optical sensor of the optical servo system at a first position relative to a selected one of recording channels on the recording head and positioning the optical sensor at a second position relative to the selected recording channel using an alignment target on the recording head.
A recording head in a read/write assembly of a magnetic recording tape system is also described. The recording head includes recording channels fabricated on a wafer and an alignment target affixed to the wafer between a first read-write element of a recording channel and a second read-write element of the recording channel, the alignment target fabricated to produce an optical reflectance signal.
