IBM set a record for data storage on magnetic tape

In March of this year, IBM managed to write data to the medium size of 1 atom, and later she set a new record in precision of speech recognition. Now the IT giant reported a new achievement: researchers broke the world record for data storage on tape drives. The recording density was increased to 201 GB of information per square inch.

Tape was invented over 60 years ago and was used primarily for the storage of analog data, documents and records of the health sector. The first tape system IBM used a spool of ribbon a half-inch wide that could accommodate only about 2 MB of data.


The IBM researchers have put 330 TB of uncompressed data, which is equivalent to 3 300 million books on the cartridge that fits in the palm. To embed information was used in a prototype magnetic tape with a metallic coating, developed by Sony. IBM employees say that the technology will be relevant at least in the next 10 years.

“Tape is typically used for storing video archives, backups, and files for disaster recovery and storing information in local storage, but the industry is working on technology in cloud storage,” commented IBM fellow Evangelos, Elefteriou.


“Despite the fact that the new tape will cost a bit more expensive than what is currently planned, the potential is huge capacity and the price per terabyte makes it attractive for cloud storage,” concluded Evangelos, Elefteriou.
