Basics

  • Create magnetic tape using iron powder and some sort of plastic film
  • Slower, but low tech to create.
  • The D-VHS standard had a capacity of 50 GB (And this may not be fully optimized due to the world jumping to optical/SSDs etc) which is comparable (at least if you only count capacity) to a cheap "thumb drive". Granted the D-VHS like format would be a bit large, but the ease of creation may make up for this.
  • The one fault off tape media is that it likes sequential access rather than random access Read this

What type of scanning to use?

  • Linear Scanning is less likely to fail, but less data storage dense
  • Helical Scanning is more data dense, but can catastrophically fail, and be hard to maintain

What type of plastic/film to use?

Size (/Format ie physical)

Size (Digital Capacity)

?mb-?gb Cassette Life Format

  • Here wikipedia discusses the application of audio cassette type formats to data storage.
  • Consumer/Portable Devices/Portable Data Collection Tools

50GB D-VHS Like Format

  • Consumer/Pro-sumer
  • VHS Form could hold quite a bit (see below) and be familiar to many devices (off the shelf or hacked)

Giant Roll of Doom

  • Beast to handle, but lots of data super cheap + easily
  • Desktop/Benchtop/Skid Mounted
  • Pro-sumer/Professional/Commercial/Industrial
