Abstract
The present invention relates to a system with read protecting function that comprises a record medium, having a data substrate with a control data zone and a data zone thereon, wherein the control data zone has a plurality of blocks, and every block has a plurality of sectors, and every sector has a plurality of bytes, and the data zone has encoded data, as well as a control code is disposed in the one of the sectors in control data zone; an optical storage device, for loading the record medium and reading and identifying the control code, then decoding the control code and outputs the decoded data if the control code is identifiable; or directly output the encoded data if the control code is not identifiable. Furthermore, the present invention relates to a method for protecting a record medium.
Claims18
A system with read protecting function, comprising:
- a record medium, having a data substrate with a control data zone and a data zone thereon, wherein said control data zone has a plurality of blocks, and every block has a plurality of sectors, and every sector has a plurality of bytes, and said data zone has encoded data, as well as a control code is disposed in said control data zone;
- an optical storage device, having a decoding mechanism for loading said record medium and reading and identifying said control code, then decoding and outputting said decoded data if said control code is identifiable;
- or directly outputting said encoded data if said control code is not identifiable.
A method for protecting a record medium, which comprises the steps of:
- providing a record medium, wherein said record medium has a data substrate with a control data zone and a data zone thereon, wherein said control data zone has a plurality of blocks, and every block has a plurality of sectors, and every sector has a plurality of bytes, and said data zone has encoded data, as well as a control code being written to one of said sectors in a control data zone;
- encoding data then writing to said data zone;
- providing an optical storage device with a decoding mechanism;
- loading said record medium into said optical storage device;
- and
- said optical storage device reading said control code and identifying said control code, then decodes said encoded data then outputs if said control code is identifiable;
- or directly outputs said encoded data if said control code is not identifiable.
