Patent ID: 7580611

Claim:
A data reproducing device comprising: a reading unit reading a plurality of data files recorded on a removable record medium; a storing unit nonvolatilely storing select information provided for each said record medium and indicating for each of said plurality of data files whether the data file is to be selected as a reproduction target or not; and a reproducing unit reproducing the data file selected based on said select information, and changing said select information not to select said selected data file in subsequent reproducing operations when said selected data file is not reproducible, wherein said reproducing unit includes a display unit displaying data information relating to said plurality of data files, an input unit receiving a select signal provided from a user when said user selects the data file to be reproduced based on said data information, a control circuit operating, when said select signal is not input from said input unit, to change said select information not to select said selected data file in subsequent selection when non-reproducibility is indicated by a reproduction result received in response to output of a reproduction instruction for said selected data file, and operating, when said select signal is input from said input unit, to change said select information not to select in subsequent reproduction a data file selected by said user for which non-reproducibility is indicated by the reproduction result received in response to output of the reproduction instruction for the data file selected by said user according to said select signal regardless of whether said selected information corresponding to the data file selected by said user indicates that the data file is selected as said reproduction target, and operating to change said select information to select the data file selected by said user in subsequent reproduction as said reproduction target if a result of reproducing the data file selected by said user indicates that the data file selected by said user is reproducible while said select information indicates that the data file selected by said user does not correspond to said reproduction target, a reproducing circuit reproducing the data file according to said reproduction instruction without outputting a picture or sound to outside, and providing said reproduction result, in the case where said select information relating to said record medium is not stored in said storing unit, said control circuit evaluates, based on an extension of each of the data files, the possibility of the reproduction for each of said plurality of data files, and stores the evaluation result as said select information on said storing unit.
