Showa Denko

Seagate this week signed an agreement with Showa Denko in a bid to secure a second source of platters for its hard drives based on heat assisted magnetic recording (HAMR) technology.

Being a vertically integrated company, Seagate has enough production capacities to continue building platters for HAMR drives...
