The method generally includes the steps of (a) recording data to the disc, (b) calculating a length of metadata based at least in part on a writing position on the disc, (c) determining a content of the metadata based at least in part on a data format and/or a disc format, and (d) recording the metadata to the disc at a position following and adjacent to the data. The apparatus generally includes (a) a disc loader configured to write data to the disc and to write metadata to the disc at a position following and adjacent to the data, and (b) a burning engine configured to send the data to the disc loader and to calculate a length of the metadata based at least in part on a writing position on the disc. The present invention advantageously allows users to view and/or share video content at any time without finalizing the disc (e.g., without recording on the lead-in area of the disc). Thus, users may append additional data to the unfinalized disc, and thereby more fully utilize space on the disc."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatus for creating and playing a playable unfinalized recordable disc","description":"Methods, apparatus, and systems for writing a playable unfinalized disc.
