Abstract: A media processing device, controls such that when a medium is transported in the inserting direction by means of transporting means, the media information recorded on the medium is read by a media information read means and stored by recording to memory. Whether or not the medium is ejectable is determined by transporting the medium in the ejecting direction by means of the transporting means. The media information stored in memory is controlled so as to be deleted when it is determined that the medium is not ejectable. In this way, as long as it is not confirmed that the medium is ejectable, the media information recorded in the medium is not output to the host device.
