Abstract: An approach, for storing video data in a plurality of tape media via a ring buffer. A tape data splitter receives video data stored in a ring buffer. The tape data splitter writes the video data to a current tape media. The tape data splitter detects an end of tape media event. The tape data splitter responds to the end of tape media event, by switching the current tape media to a next tape media. The tape data splitter selects a resume point for the video data stored in the ring buffer and writes to the next tape media, the video data stored in the ring buffer that is subsequent to the resume point.

Abstract: The present invention relates to a recording/reproducing device that records data on a double-sided recordable optical disk for storage and management purposes. The device includes a unit which stores a plurality of optical disks, a unit which records data onto and reproduces data from an upper side of an optical disk, a unit which records data onto and reproduces data from a lower side of an optical disk, a unit which conveys an optical disk between the disk storage unit and each recording/reproducing unit. When a request for reading data recorded on the lower side of the disk is received while the upper side is being written onto, a control unit interrupts a data recording process on the upper side, reproduces data recorded on the lower side, and after completion of reproducing the recorded data, resumes the interrupted data recording process.

Abstract: In an information recording method, information is recorded to semiconductor memory when at least a specified amount of free space exists in the semiconductor memory. Information is recorded to magnetic memory when the free space in the semiconductor memory is insufficient but at least a specified amount of free space exists in the magnetic memory. Information is recorded to optical memory when the free space in both the semiconductor memory and the magnetic memory is insufficient. When retrieving recorded information, an access count is incremented, and information with a comparatively high access count is moved to the semiconductor memory, while information with a comparatively low access count is moved to the optical memory. Information is thus recorded to a recording medium suitably selected from among semiconductor memory, magnetic memory, and optical memory, thereby making effective use of each memory type.
