The Linear Tape File System (LTFS), invented by IBM’s lauded Research Division, enabled major improvements in digital workflow and dramatic reductions in the costs associated with capturing, storing and repurposing media content while providing dramatic improvements in transfer rates, storage density, automated workflow, meta-data capture and content availability. Combining digital broadcast and IT standards in a broadcast environment, the LTFS has enabled real-time content recording and high-speed recovery of content to be a broadly-supported, multi-industry solution.

In a blog post
earlier this year, IBMer Tony Pearson, Master Inventor and Senior Managing Consultant for the IBM System Storage product line, wrote:
With the capabilities of LTFS, IBM has introduced an entirely new role for tape, as an attractive high capacity, easy to use, low cost and shareable storage media. LTFS can make tape usable in a fashion like removable external disk, a giant alternative to floppy diskettes, DVD-RW and USB memory sticks with directory tree access and file-level drag-and-drop capability. LTFS can allow the for passing of information around from one system or employee to another. And as for high video storage capacity, a 1.5TB LTO-5 cartridge can hold about 50 hours of XDCAM HD video!”
Lead researcher on the project David Pease is a long time storage research expert at the Almaden lab in San Jose, CA. Pioneering many of the tape and disk storage technologies out of IBM Research over the last decade, David recalls a significant factor in deciding to pursue this project the way he did. “We really needed to make the first version open source,” David said. “The idea of a file system that was cross-platform and interoperable was key; we wanted people to have an interface they were familiar with, similar to disk with file folders, drag and drop and double-click, but we also wanted to make sure it wasn’t tied to only Windows or only Unix. The real future for acceptance for just about any kind of storage technology is interoperability and that people aren’t tied to a platform.”
David and his team developed LTFS from concept to fruition in just less than 3 years. An impressive feat in the research world, he shares some thoughts about winning an Emmy for his work:
First, I am truly stunned. This recognition is more than we ever expected so early in the project, and hopefully it reflects the importance of what we’ve done. When we started this work, we said that our goal was to change the tape industry and the Media and Entertainment business; it seems that we are well on the way to realizing these goals.
I have to point out that an idea and project like this are never the work of an individual. From Ed Childers and the other tape experts in Tucson, to the folks at Almaden who encouraged me to get involved with tape (again), to the team of great researchers and developers who worked on this in my group, to the tape specialists in the Yamato Lab who joined my team or worked to support it, I have to say that we couldn’t have gotten here without the efforts of each of you. Thank you all
for making this possible!
