Abstract
Shingle-write is the technology to achieve higher track density without reducing head pole. Because the write-ability limit due to narrower track width is the key challenge, breakthrough against the write limit is the purpose in not only HAMR and MAMR but also BPM and Shingle-write. The concept, pros and cons on Shingle-write based on activities in the Storage Research Consortium (SRC) is discussed in this paper.
