Write pole formed with evaporation deposition

Write pole formed with evaporation deposition

A write pole may be formed by first depositing a dielectric layer onto a substrate and then patterning the dielectric layer to form a trench with a write pole shape. The trench is subsequently filled with the evaporation deposition of a magnetic material to form a write pole. The trench may have a g...

Zusammenfassung:A write pole may be formed by first depositing a dielectric layer onto a substrate and then patterning the dielectric layer to form a trench with a write pole shape. The trench is subsequently filled with the evaporation deposition of a magnetic material to form a write pole. The trench may have a greater depth dimension than width dimension.
