A digital media apparatus that includes a player and media storage member wherein the apparatus facilitates controlled transmission of digital audio data stored on the media storage member. The player of the present invention includes a receiving area configured to releasably receive and retain a media storage member. The media storage member is operably coupled to the player utilizing a plurality of electrical contacts. The housing of the media storage member has a recess in the upper surface thereof that is configured to receive a graphic art member. The graphic art member is backlit by an illumination element disposed in the housing of the media storage member. A first set of control switches and second set of control switches are located in the media storage member and receiving area respectively and place in an operational mode the apparatus to permit playing of the audio files.

A card reader is provided which is capable of detecting a skimming magnetic head attached to a front side of a card insertion member formed with a card insertion port and a skimming magnetic head attached to an inclined face of the card insertion port with a simple structure. The card reader includes a card insertion member 8 formed with a card insertion port 3 and a light emitting element 9 and a light receiving element for detecting that a foreign matter has been attached to the card insertion member 8. A lower face of the card insertion port 3 is formed to be an inclined face 3a which is inclined toward a lower side as going to the front side.
