Patent number: 10897593Abstract: 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.Type: GrantFiled: August 30, 2016Date of Patent: January 19, 2021Assignee: International Business Machines CorporationInventors: Hiroshi Araki, Shinobu Fujihara, Tohru Hasegawa, Takeshi Ishimoto, Hiroshi Itagaki, Hiroyuki Miyoshi, Yutaka Oishi
