Magnetic recording & device material

Magnetic recording material is always progressing such as HAMR (Heat
Assisted Magnetic Recording Media) Media and BPM (Bit Patterned Media).

We develop sputtering targets not only for advanced magnetic recording media but also for Magneto Resistive Device and MRAM.

We respond to customers' needs precisely.

DTR (Discrete Track Recording Media

Existing PMR discs

Existing PMR discs

Due to interference between tracks, current PMR discs are not narrowed track pitch.

DTR discs

DTR discs

Due to forming patterns between tracks, DTR discs can increase recording density. Memory capacity of DTR is 1.5 times more than current PMR discs.
