Nanomaterials for Smart Data Storage

Lead Research Organisation: University of Southampton
Department Name: Optoelectronics Research Ctr (closed)

Abstract

Demand for data storage continues to grow at over 40% per annum, in part as a result of increasing movement of data to
the cloud. All segments of the hard drive market remain in demand and the recording transducer is critical for storage
capacity. A total of 25% of the world's transducers are manufactured in the UK thus we have a unique opportunity to grow
this market as demand for this highly complex nanoengineered component increases. This project will deliver smart
nanophotonic materials to be used in the writer for the next hard drive technology transition using Heat Assisted Magnetic
Recording, due in 2018. The very high performance demands and fluctuating operating temperature make reliable
operation difficult to achieve in prototype devices today. The solution is to make this key component from smart materials
which self-compensate for these thermal effects as well as providing other functionality. The UK has world class capability
in the area of nanophotonics (UoS) and material discovery and optimization (Ilika) and this project provides an opportunity
to develop these materials for improved product performance and competitiveness for the manufacturing business of end
user Seagate.

Planned Impact

The proposal addresses an area of significant national importance and addresses several EPSRC priorities in Advanced
Materials, Photonics for Future Systems, Towards an Intelligent Information Infrastructure, Quantum Technology Hubs and
physics grand challenges and Nanoscale Design of Functional Materials.
Our proposal will make a significant contribution to the training of a mid-career post-doctoral researchers, Dr Chung-Che
Huang (ORC) who will be mentored by Professor Hewak. Other post-doctoral students and PhD students working in
related areas will also benefit. Our proposal compliments that of several research groups in the UK and our results will
feed into and strengthen the UK foundation in this area.

We will disseminate our overall results in high-impact journals and will present this interdisciplinary work at a wide range of
conferences such as (E-)MRS (materials), CLEO and LEOS (optoelectronics), Semicon West and EPCOS (electronics),
SPIE Photonics West (opto-semiconductors) and ICANS (amorphous semiconductors).
Results of the research will be exploited through the Research and Innovation Services (R&IS) group at Southampton. We
aim for the first technological outputs of this programme to demonstrate commercial potential by the end of the project and
would look for routes to bring successful work to market. To this end we will focus on strengthening our links with future
exploiters including our previous licensee, Ilika Technologies Ltd. We will also pursue entrepreneurial and start-up activity
with Set Squared.

Description Evaluation of materials we have synthesized by industry in the UK and USA.. The consortium provided Southampton with valuable experience working with industrial partners. It continued to build a relationship with Ilika Technologies Ltd, expanding its interactions to new families of materials and application spaces. Working with Seagate (Ireland) Inc provided a unique opportunity to engage with a large multinational and world leading manufacturer of specialized electronics. To gain insight how such organizations undertake higher TRL level research provided useful experience which will benefit our future interactions with industry and manufacturing in the UK. Seagate will use the nitride material developed within this project as part of the HAMR transducer in HAMR hard drive product in early 2019. Ilika will publish many of the results from nitride optimisation work carried out within the project and determine if this is of interest to other companies with the semiconductor and photonics industries. Southampton will continue to disseminate results through conference presentations, workshop, invited talks and publications, where it is able to under the terms of our intellectual property agreement. It will continue to utilize knowledge gained in its internal research programme.

PI Contribution HAMR is a technology designed to enable the next big increase in the amount of data that can be stored on a hard drive. It uses a new kind of media magnetic technology on each disk that allows data bits, or grains, to become smaller and more densely packed than ever, while remaining magnetically stable. A small laser diode attached to each recording head heats a tiny spot on the disk, which enables the recording head to flip the magnetic polarity of each very stable bit, enabling data to be written. Our research team provided expertise in our knowledge of advanced materials to the industrial partner Seagate to help them indentify materials more suitable in the hard drives they were developing.

Advanced material synthesis and test capability at the partner organisations, Ilika and University of Southampton was used to facilitate material optimisation and exploration with many alternative options. The Nanomaterials for Data Storage has resulted in strong working relationship between Seagate, llika and the University of Southampton. As a result of this another Innovate UK funded project, Photonic Material Process for Data Storage, is underway. The aim of this project is to put in place a mechanism for continued business interaction between Seagate and Ilika. Also, the University of Southampton has been able to quickly demonstrate material properties and measurements in several areas that are of interest to Seagate. It is hoped that one of these areas can become the focus on a future Innovate UK funded project. The partners are actively working on this at the moment.
