摘要： A liquid discharge head is arranged in a manner that in the cross section of a discharge port in a liquid discharge direction, the discharge port includes: at least one projection that is convex inside the discharge port; a first area, for holding a liquid surface connecting a pillar-shaped liquid that is elongated outside the discharge port; and second areas where a fluid resistance is lower than that in the first area so as to pull the liquid in the discharge port in a direction opposite to the liquid discharge direction; and the first area is formed in the direction in which the projection is convex, and the second areas are formed on both sides of the projection.

摘要： According to one embodiment, a magnetic recording head includes a spin-torque oscillator between a main pole and a trailing shield. An oscillation layer of the spin-torque oscillator is formed by repeatedly stacking two or more laminates each including a metallic magnetic layer of a body-centered cubic crystalline metal and a metallic magnetic layer containing cobalt. The film thickness of each metallic magnetic layer is more than 0.2 nm and not more than 3 nm. The intensity of an anisotropic magnetic field is higher than a value obtained by subtracting the intensity of a gap magnetic field from the intensity of a diamagnetic field and lower than the intensity of the diamagnetic field.
