1. An information processing apparatus comprising:
a storage section configured to store subsequent data subsequently acquired or generated as data corresponding to a medium stored content, the subsequent data comprising first subsequent data and second subsequent data; and a control section configured to execute a management process of managing the subsequent data with respect to the storage section, the control section being configured to execute, as the management process of the subsequent data,
a first process of recording first subsequent data descriptive information and first subsequent data management information corresponding to the first subsequent data, the first subsequent data descriptive information comprising type information of the first subsequent data, medium identification information, and title identification information, the first subsequent data management information being recorded in a manifest file, the recording occurring at a time of recording the first subsequent data in the storage section,a second process of generating display data based on the first subsequent data descriptive information, anda third process of reproducing or deleting the first subsequent data in response to user designation information for the display data, wherein the third process comprises, in a case where the user designation information designates deletion of the first subsequent data and the manifest file comprises second subsequent data management information corresponding to the second subsequent data, obtaining an updated manifest file and recording the updated manifest file in the storage section.
