The invention relates to a record carrier having a data zone (7) and an initial zone (25) and comprising a main channel storing content and a side channel storing address information and data relevant for making recordings. It further relates to methods and devices for protecting content stored on a record carrier and for reading out protected content. To provide a record carrier with content protection information (20, 22, 24, 26, 28) stored on it, which can be used with legacy devices without causing confusion, which can substantially be produced without extra production steps and which can be easily read by common devices, it is proposed to store said content protection information (20, 22, 26, 28) for protection of said content in said side channel in said data zone (7).
