US Patent 7934195 Method for controlling the propagation of metadata items

A method enables and controls automatic propagation of metadata items to a recording media or to devices for reading from or writing to recording media. The metadata items are provided with a propagation property, which defines to which recording media or to which devices the metadata items shall propagate, and on which recording media or in which devices the metadata items shall be stored. At least when a recording medium is inserted into or removed from a device, or when the device is powered up or down, the metadata items are automatically propagated and stored in accordance with the propagation property.
