Microwave Assisted Magnetic Recording (MAMR) has been developed, one of the energy assisted magnetic recording technologies which can increase the recording density of HDDs. In this talk, we present an overview of two types pf MAMR technology: A Flux Control MAMR (FC-MAMR) which we have originally developed, and a Microwave Assisted Switching MAMR( MAS-MAMR) which is based on the ferromagnetic resonance phenomena.
