Abstract
An information device includes a slider (100) including a first metal antenna (103a), a second metal antenna (103b), and a heater (107) configured to vary the distance between the first metal antenna (103a) and the second metal antenna (103b) in a direction orthogonal to a track direction on the surface of a disk (104), and an arm motor (120) configured to move the slider (100) in parallel to the surface of the disk (104). The arm motor (120) and the heater (107) cause the first metal antenna (103a) and the second metal antenna (103b) to respectively follow corresponding target tracks.
