Abstract
A recording-and-reproducing apparatus for managing content data recorded on a removable recording medium includes: a device configured to acquire reproduction information required for reproducing the content data; a device configured to generate a first management file for individually managing the content data; a device configured to register control information for the content data in a second management file collectively managing the content data. Further, the apparatus includes a device configured to read out the control information in the second management file recorded on the recording medium; a memory in which the control information of the second management file read out by the read-out device is expanded; a device configured to compare the control information in the second management file expanded in the memory and the content data recorded on the recording medium; and a device configured to update the control information in the second management file expanded in the memory.
