TAPE vs HDD
Future Tape Technology
The INSIC roadmap states that the capacity of one tape cartridge in 2029 is 723TB, the recording density (278Gbpsi) at this time is about the same as that of HDD products in 2008. 1PB cartridge may become a reality in the future.
SECURITY
Cyber Attacks and Tape Storage
Damages from cyber attacks have increased significantly since last year. Tape cartridges can be removed and stored offline, the physically separated "air gap" protects the data from unauthorized encryption and tampering.
TECHNOLOGY
Is Tape Really an Old Technology?
Some people still think tape is an old technology with many trouble handling. However the latest LTO tapes are made from components with strong durability, going through many environment testing before shipment.

As it provides lower cost per gigabyte and requires almost no electricity in storing data, tape technology continues to be the most cost-effective solution for long-term data retention, including storage space, energy use and equipment. The TCO of tape systems are about one-third of that compared to disk storage.
Tape storage offers a strong error protection and correction algorithm, with an error rate of 1 bit in 1x10E19 bits- or one error in every 10,000 petabytes of recorded data. This is 1000X better than disk, whose error rate is 1 bit in 1x10E16 bits or one error in every 10 petabytes.
Tape storage reduces risks of data corruption, deletion, or unauthorized disclosure by creating "air gap” (separating data on tape from on-line data stores). Compared to the shelf-life of disk (3-5 years), LTO tape media can withstand the test of time, providing users with a shelf-life of up to 50 years.
With the particle forming technology, FUJIFILM successfully densified particles by dispersing and arranging them evenly. This has dramatically improved the recording density. There are even more new particles currently in development, from the current mainstream Barium Ferrite to a more refined Strontium Ferrite.
Producing magnetic tape requires nano-level precision. The nano-dispersion technology are used to ensure uniform dispersion of the particles. Liquefied magnetic particles are mixed with special beads, and then coated so that each magnetic particle doesn’t stick to one another.
High-density digital recording requires an extremely thin recording layer. Micronized magnetic particles are then applied to the base film. A drop of the material is spread over one square meter under high-speed coating. The process requires techniques that enable such thin and even application.
After the coating process, the magnetized base film is cut with extreme precision. FUJIFILM's advanced tape-slitting technology ables to cut kilometers long tape to a mere 12.65 millimeters in width with a margin of error of plus-minus 0.005 mm per ½ inch.
Tape storage technology relies heavily on high-precision servo control to achieve its remarkable capacity. LTO data cartridge uses dual servo tracks that have been precisely written along the entire length of each of its four data bands for placement control and redundancy.
