Abstract
A hybrid card comprises a substrate carrying an IC chip. An IC terminal is electrically connected to the IC chip and is arranged on a first surface of the substrate. A contact region is defined around the IC terminal and is occupied when a contact terminal of a recording/reproducing apparatus electrically contacts the IC terminal. An optical recording region has a plurality of tracks extending parallel to each other on the first surface. The contact region and the optical recording region are spaced apart in a direction parallel to the tracks.
