1. A data storage medium readable by a designated data rendering system, said medium comprisinga main data storage area configured to store main data and a data usage agreement;
- anda modifiable structure separate from the main storage area configured to be altered in a controlled and verifiable manner by an external influence, wherein the alteration is detectable by said designated data rendering system, and said alteration permanently corrupting at least part of the stored data to enforce at least one restrictive covenant of the data usage agreement, and wherein the stored main data is not accessible by the designated data rendering system until the modifiable structure is altered.

12. A data rendering system for rendering content delivered on a data storage medium having a main data storage area and a modifiable structure separate from the main storage area enabled for controlled and verifiable alteration by an external influence in a manner detectable by said system, the system comprising:
-
a reader that reads data stored in said data storage medium, the stored data including main data and a data usage agreement associated with the main data; a memory cell that stores access data designated to be permanently corrupted as a result of said medium alteration; an alteration detector that determines whether said data storage medium has been altered, wherein the determined alteration of the data storage medium renders access data previously stored in the data storage medium inaccessible by the system; and a logic unit programmed to deny access to the stored main data upon detecting at least one event out of a plurality of events comprising; an alteration of said medium has not been confirmed by said alteration detector, access data permanently corrupted as a result of controlled and verifiable medium alteration is not present in said memory cell, and at least one restrictive covenant of said content usage agreement is not satisfied. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A method to distribute content stored on a removable data storage medium enabled for controlled and verifiable alteration by an external influence in a manner detectable by a data rendering system, said method comprising:
-
delivering a medium storing content associated with access data to the data rendering system; storing at least part of the access data in said system; altering said medium to render at least part of the access data unreadable, wherein at least a portion of the content is inaccessible before said alteration; testing said medium for said alteration; and retrieving at least part of the content from said medium using the access data stored in said system. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38)

39. An optically readable data storage medium comprising at least one structural weakness for irreversible alteration by an external mechanical force in a manner detectable by a designated data rendering system, said alteration permanently corrupting at least part of data stored in the medium with a purpose of enforcing a data usage agreement wherein at least part of the stored data is not accessible by the designated data rendering system until the alteration is detected.
-
40. A data storage medium comprising:
-
a main data storage area configured to store main data; and an alterable structure separate from the main data storage area and configured to store access data separate from the main data that is used to access the main data, wherein alteration of the alterable structure renders the access data inaccessible and the main data accessible. - View Dependent Claims (41, 42)
