Sony – thank you for the tape you gave to me

IBM has claimed its fifth-in-succession world tape density record with a 330TB raw capacity technology using Sony tape media tech.

Back in April, 2015 IBM and Fujitsu demonstrated a 123 billion bits/in2 220TB tape using so-called Nanocubic technology and barium ferrite tape media.

This time around, IBM's tape drive researchers are working with Sony Storage Media Solutions and its sputtered media.

Engineering developments have enabled an areal density of 201Gb/in2.

New signal-processing algorithms for the data channel, based on noise-predictive detection principles, enabling reliable operation at a linear density of 818,000 bits per inch with an ultra-narrow 48nm-wide tunnelling magneto-resistive (TMR) reader.
