Abstract
Abstract A data storage device is disclosed having a data input circuit 13, 16, a data output circuit 14, 16 and a power supply circuit 11, 12, 15 all housed in a housing. The power supply circuit includes a coil 11, located internally on the housing without a physical connection to the exterior of the housing for receiving power from outside the housing by inductive coupling through the housing from a power supply coil forming part of a host device. Preferrably data is transmitted to and from the data storage device by means of radiation responsive elements 13, 14.
