ABSTRACT:
A content recording apparatus that writes, when a recording instruction is issued, into a first area of a recording medium predetermined information indicating a predetermined value, records into a plurality of partial areas sporadically distributing in a second area of the recording medium a content to which a plurality of markers are assigned in a predetermined manner, and after completing recording the content, writes into a third area of the recording medium link information indicative of a link state among partial areas in which the content is recorded, and updates a value indicated by the predetermined information written in the first area, includes: a predetermined information detector for detecting the latest predetermined information out of the predetermined information written in the first area when a driving power is input; an area detector for detecting from the second area partial areas in a non-link state based on the link information written in the third area when the predetermined information detected by the predetermined information detector indicates the predetermined value; an information creator for creating link information indicative of a link state among the partial areas detected by the area detector; a marker detector for detecting the markers from the partial areas detected by the area detector; and a writing/updating processor for writing into the third area partial link information based on a detection result of the marker detector out of the link information created by the information creator, and updating a value indicated by the predetermined information detected by the predetermined information detector.
