Abstract
Embodiments of the present invention provide a technique for projecting both a write element portion in writing and a read element portion in reading, and controlling a projecting distance of each write element and read element. According to one embodiment, a light absorbing member and a thermally expanding member are formed near a read element, and light is irradiated to the light absorbing member, thereby a read element is projected. Alternatively, light absorbing members, which absorb light having different wavelengths from each other, and thermally expanding members are formed near a write element and near the read element respectively, and a wavelength or intensity of light to be irradiated is changed, thereby a projecting distance of each of the write element and the read element is individually optionally controlled.
