摘要:
A ferromagnetically coupled magnetic recording medium having a first ferromagnetic layer, a second ferromagnetic layer, and a ferromagnetic coupling layer to ferromagnetically couple the first ferromagnetic layer to the second ferromagnetic layer is used as stable magnetic media with high MrT in high density recording hard drives. The first ferromagnetic layer is the stabilization layer and the second ferromagnetic layer is the main recording layer. The ferromagnetic coupling layer comprises a conductive material having a thickness which produces ferromagnetic coupling between said first ferromagnetic layer and said second ferromagnetic layer via the RKKY interaction.
摘要:
In a piezoelectric drive comprising clamping piezo packets which are adjacently arranged, under compressive pre-stress, between a reference part and an output part, the reference part is connected to the clamping piezo packets by means of a “semi-rigid” bridging plate, which adapts in a flexible manner to differences in stack height of the piezo packets, in a static state but remains essentially rigid in a dynamic state, that is, at the operating frequency of the drive.
