This time, all applaud for the IBM scientists. The reason being the recent world record formed by them, which states that 330 terabytes of uncompressed data i.e. almost equal to 330 million books, can be easily fit into a cartridge that’s almost the size of a human palm.
IBM researchers have set this new record of 201 gigabits per square inch of data stored on a Sony prototype of ‘sputtered magnetic tape’. Now this tape is further enhanced by paintings on several thin layers of barium ferrite liquid metal using a process, same to the one used in the production of integrated circuits. Also, the use of metal remained unaltered for the sputtering process to store 123 gigabits per square inch on tape, like the one in 2015.
Tapes were always cheaper than disks and are simply the reason why it can store quite a considerable amount of video archives and troves of records, which according to the enterprises, in health and finance are obliged to keep for compliance.
IBM, one of the world’s largest enterprise tape vendors with a history of almost 60 years, is quite optimistic about the fact that this sputtered tape technology will win back the confidence of the customers for depending on cheap tape for the next decade.
Right now, quite a good news in the context of tapes, is the rise of recorded video surveillance data, which has aided HP, IBM and Quantum ship 96,000 petabytes of compressed capacity the year before.
IBM also foresees the potential for tape technology in Amazon and Google, in the form of cold storage and cloud services.
Lastly, IBM Fellow Evangelos Eleftheriou ended by stating that, “While sputtered tape is expected to cost a little more to manufacture than current commercial tape that uses barium ferrite, the potential for very high capacity will make the cost per TB very attractive, making this technology practical for cold storage in the cloud”.
