A reproducing apparatus has three reproducing modes that are a first mode, a second mode, and a third mode. In the first mode, when a program that has been reproduction restricted is tried to be reproduced, the reproducing operation is paused and the user is asked whether he or she wants to reproduce the program. Corresponding to the user's reply, the reproducing operation is performed or prohibited. In the second mode, a program that has been reproduction restricted is prohibited from being reproduced. In the third mode, a program that has been reproduction restricted is unconditionally reproduced. When the power of the apparatus is turned on at step S, a prompt that causes the user to select one of the first mode, the second mode, and the third mode is displayed. At step S, a process for designating a mode is performed. Information of the designated mode is stored in a nonvolatile memory.
