First position information indicating a position is acquired at a first time. Second position information indicating a position is acquired at a second time that is later than the first time. The first position information and the second position information are compared to determine whether or not a reproduction apparatus is moved. Information is stored in a recording medium in a first mode if it is determined that the reproduction apparatus is moved and the information is stored in the recording medium in a second mode different from the first mode if it is determined that the reproduction apparatus is not moved. The first mode is a reproduction mode having functions for use in reproduction more restricted than the second mode.
