Data storage and reproduction apparatus storing and reproducing multimedia data

摘要

An HDD (5) is divided into a segment area (51) storing multimedia data, an information file area (52) storing an information file of a file, and a system information area (53) storing a system information file. Storage of the system information file in the system information area (53) and storage of the information file in the information file area (52) are performed every prescribed time (X seconds), instead of a time point when recording and/or reproduction is stopped. If an apparatus suddenly stops, a location where damage is likely in the HDD (5) can be detected by referring to the information file area (52) and the system information area (53).
