CLV carrier copy protection system

A continuous linear velocity (CLV) storage medium having at least one file stored on said CLV storage medium;

• the CLV being immunized against an unauthorized duplication;
• the CLV includes a plurality of consecutive blocks, each including a data section and control section;
• the control section includes at least one error correction, and at least one error detection code;
• said blocks are configured in a given format;
• at least one of said blocks includes modified data in the data section constituting modified data section;
• said modified data constituting reconfigured format which violate said given format;
• the control section associated with said modified data section is modified such that at least said error correction or said error detection codes substantially match said modified data section.

A real-time error handling produce associated with a continuous linear velocity (CLV) storage medium having at least one file stored therein;

• the CLV includes a plurity of consecutive blocks, each including a data section and control section;
• the control section includes at least one error correction, and at least one error detection code;
• said blocks are configured in a given format;
• the real-time error handling procedure is adapted to executed the following steps, that include:
• a) detecting modified data in the data section of at least one block;
• said modified data constituting reconfigured format which violate said given format;
• b) checking that the control section associated with said modified data section is modified such that at least said error correction or said error detection codes substantially match said modified data;
• c) in the case that at least the conditions of said steps (a) and (b) are met, classifying said CLV as an original CLV, and otherwise classifying said CLV as an unauthorized duplication.

A continuous linear velocity (CLV) storage medium having at least one file stored on said CLV storage medium;

• the CLV being an unauthorized substantially duplication of an original CLV;
• the CLV includes a plurality of consecutive blocks, each including a data section and control section;
• the data section of said blocks including a data constituting a file;
• said file is rendered inoperable since at least a portion thereof accommodated in said original CLV is absent in said unauthorized duplication of said CLV.
