To provide an information processor which prevents a miss of a desired program by zapping, in which reproduction of the desired program after termination of the zapping is simplified and convenience is improved.

The information processor performs registration setting of an anchor program (S401), next, detects whether or not program change from the anchor program to the other program is performed (S402) and starts recording for the anchor program (S403), when the program switch is detected. The information processor detects whether or not switching from the other program to the anchor program is performed during recording (S404) and when the switching to the anchor program is detected, the processor reproduces recording data of the recorded anchor program from the head while continuing the recording of the anchor program (S405).
