This week Chris and Martin take the opportunity to grill (not broil) Matt Starr from Spectralogic to learn everything about magnetic tape. This episode came out of a discussion with Chris Mellor (episode #176) in which we asked the question why tape media doesn’t wear out. The answer is obviously within the podcast so you’ll need to listen to find out!
In this conversation, the team look back at the evolution of tape but more importantly what we can expect in the future. Magnetic tape is more of an archive offering these days (although ransomware has made it more popular for air-gapping backups). It seems tape has a long future as the lowest cost storage medium with lots of innovations still to come.
You can learn more about Spectra Logic over at https://spectralogic.com/. The featured image for this episode is a single 44-cabinet tape library as mentioned in the podcast that was taken at a Spectra Logic event in 2013.
