| 摘要 |
<p>The present invention relates to a system with read protecting function that comprises a record medium (10), having a data substrate (11) with a control data zone (111) and a data zone (112) thereon, wherein the control data zone (111) has a plurality of blocks (113), and every block (113) has a plurality of sectors (114), and every sector (114) has a plurality of bytes, and the data zone (112) has encoded data, as well as a control code (115) is disposed in the one of the sectors (114) in control data zone (111); an optical storage device (20), for loading the record medium (10) and reading and identifying the control code (115), then decoding the control code (115) and outputting the decoded data if the control code is identifiable; or directly outputting the encoded data if the control code (115) is not identifiable. Furthermore, the present invention relates to a method for protecting a record medium (10).</p> |
