Abstract: A recording medium includes a recording layer. The recording layer includes an aliphatic polymer, and a multiphoton absorption compound containing at least one bond selected from the group consisting of a carbon-carbon double bond, a carbon-nitrogen double bond, and a carbon-carbon triple bond, and having a multiphoton absorption characteristic. When the thickness of the recording layer is 100 μm, the transmittance of the recording layer in the thickness direction with respect to light having a wavelength of 405 nm is greater than or equal to 80%.

Abstract: An actuator device comprises an actuator wire, a net-shaped heating element which covers a side surface of the actuator wire and comprises heating wires, and a controller for supplying electric power to the net-shaped heating element to heat the net-shaped heating element. The actuator wire is contracted by application of heat and restored by release of the heat. The side surface of the actuator wire is formed of a polymer. One end of the net-shaped heating element is connected to an end of the actuator wire. Another end of the net-shaped heating element is connected to another end of the actuator wire. Each of the heating wires comprises an insulative first elastic yarn and a metal wire. The metal wire are helically wound onto the first elastic yarn. When the net-shaped heating element is not heated, the net-shaped heating element is in contact with the side surface of the actuator wire. When the net-shaped heating element is heated, the net-shaped heating element moves outward from the side surface of the actuator wire due to contraction of the actuator wire.
