The next generation HDD technology called pattern media will enable the increase of storage capacity significantly. A key challenge to realize pattern media is the manufacturing of the pattern in a cost effective manner. By concluding both simultaneous double-sided imprint capability as well as small feature replication Obducat takes a significant step forward and there by secures the targeted production capacity and cost.

By successfully adjusting its NanoImprint tools for next generations of hard disk drives based on discrete track recording (DTR) and bit pattern media (BPM), Obducat now have the capability to simultaneously print hard disk substrates on both sides including center hole alignment using the unique Soft PressT technology and IPS-STU process.

Furthermore, 17 nm dots have been printed uniformly with a residual layer below 7 nm. The capacity of the Sindre HDD high volume manufacturing system targets the requirements of the hard disk industry having a throughput of 1200 disks/hour.

"Through this development we will be able to leapfrog the industry and confirm our position as market leader. Our customers in the HDD industry are very positive to progress we are making", says Patrik Lundstrom, CEO of Obducat AB.
