Material DesignTechnology

Design functional materials by understanding the functional expression and physical property control factors.

Resin Design: Technology that controls the higher order strures and physical properties of resins

Multilayer Base Materials

Low ETC,low elastic resins with structure control

As an example of resin design for multilayer base materials, controlling the two-component system structure consisting of high- and low-elasticity segments enables the materials to achieve both high-heat stability and low thermal-expansion coefficient properties.

Energy Assisted Magnetic Recording

Possible solution to overcome the magnetic recording trilemma*1

Assisted Recording New recording scheme to enhance writability by applying heat/microwave to the medium.

HAMR: Heat Assisted Magnetic Recording
  • HAMR uses near-field light to locally heat a recording layer to assist magnetization reversal.
MAMR: Microwave Assisted Magnetic Recording
  • MAMR applies a microwave field to a recording layer to reduce the magnetic field to reverse magnetization.

By optimizing media design for those assisted recording schemes, areal density up to 5-6Tbit/inch2 can be expected in the future.
