This article presents a high precision measurement of the proximity shift on a magnetic transition due to the presence of an old transition in the background. Using peak detection electronics, we deduced this interpattern shift by measuring the distance between a reference and a test transition in a multibit pattern, with and without a background transition in the vicinity of the test transition. The measurement process was carefully designed to achieve high accuracy. We measured the proximity shift of a 3380‐type write head on disks with different remanent‐thickness product for cases of both easy and hard transition types for both the background and the data transitions. Results showed three distinct transition shift behavior depending on the background‐to‐test intertransition distance: a gradual decay in the far region (≳2 μm), a rapid rise in the intermediate region and asymptotic saturation at the near region when the two transitions are almost on top of each other. The asymptotic shift magnitude agre...
