摘要： An apparatus for recording an information signal on a record carrier where the record carrier has a first and a second tracking signal of specific frequencies and wavelengths. The tracking signals are recorded in respective first and second tracks which run parallel to each other in their longitudinal direction on the record carrier. The apparatus is provided With a receiver for receiving the information signal, and a converter for converting the information signal into a channel signal. The channel signal includes signal blocks of information with each signal block including a portion of the information signal. A writing head writes the channel signal in a third track on the record carrier. A reading head is adapted to read at least one of the first and second tracking signals from the first and second tracks. A generator generates a control signal from the at least first and second tracking signals read from the record carrier. The apparatus is adapted to record the information signal on the record carrier so that the length of a signal block of the channel signal is equal to an integer multiple of the wavelength of one of the first and second tracking signals.
