A magnetic recording medium having increased thermal stability and signal-to-medium noise ratio, comprising a layer stack including, in sequence:. The flexible display panel is disposed above the supporting substrate. A method for fabricating the component includes the steps of providing a substrate containing multiple dice, forming trenches on the substrate proximate to peripheral edges of the dice, and depositing a polymer material into the trenches. An emitter DOA unit vector or COS is estimated and an LBI phase difference is predicted.
