Seagate Signs HAMR Deal with Showa Denko: Secures Second Source…

Seagate this week signed an arrangement with Showa Denko in a bid to safe a second resource of platters for its tough drives based mostly on heat assisted magnetic recording (HAMR) technological know-how. Under the terms of the offer, Seagate will consider SDK’s current resources for HAMR media and the two corporations will jointly acquire future components. 

Seagate commenced to ship its Exos HDDs that includes HAMR within its Lyve storage techniques late last yr. These tough drives use crucial components, this sort of as recording heads with a around area transducer that heats up the media as effectively as glass platters with an FePt magnetic layer, produced and designed completely in-home. Remaining a vertically integrated corporation, Seagate has more than enough generation capacities to keep on creating platters for HAMR drives internally, but having a 2nd supply for a crucially crucial ingredient makes a good deal of sense for higher-quantity merchandise. 

Obtaining spent around 10 decades on HAMR pathfinding and exploration, Showa Denko formally began to acquire its glass platters for HAMR HDDs in February, 2020. Back again then, the firm said that HAMR would attain areal density of 5-6 Tb/in2 in the long run, enabling three.5-inch really hard drives with 8 or nine platters to retail store 70 TB – 80 TB of data. 

By now, Showa Denko has finished growth of its to start with HAMR media materials featuring a FePt magnetic alloy and engineering to mass-develop tricky drive platters. Underneath the phrases of the agreement between SDK and Seagate, the difficult travel maker will appraise the content designed by the Japanese firm. Heading forward, Seagate and SDK will jointly establish new magnetic alloys for HAMR HDDs.

For now, Seagate will proceed employing its individual FePt glass media inside of its HAMR HDDs, but if it finds Showa Denko’s HAMR media good enough, it could use it for long term tough drives.

The deal among Seagate and Showa Denko makes sure that the hard drive maker will have two sources of HAMR platters in the long term, which will be significant if Seagate substantially expands utilization of its HAMR technologies. In simple fact, when HAMR media hits specific areal density (i.e., substantially greater than PMR’s 1.14 Tb/inchtwo), it will make a wonderful perception to adopt the engineering nor only for highest-potential HDDs, but also for midrange HDDs to lower down their costs.

“[HAMR] is not only about the highest capacity stage,” said David Mosley, CEO of Seagate, at a conference very last yr. “If we can help you save a disk and two heads in a 16 TB drive, we will glimpse at executing that as effectively. So, it is genuinely throughout the entire portfolio, which is why we think that this platform play is so significant. We can introduce HAMR into the similar platform. The charge will increase are actually nominal.”

Furthermore, Seagate will also make sure that SDK-designed HAMR platters will be appropriate with its HAMR implementation, which could come to be the firm’s competitive edge against Toshiba and Western Electronic at the time they adopt this engineering.

“We be expecting this alliance will even more speed up technological development pioneered by the two companies,” a statement by Showa Denko reads.

For Showa Denko, the world’s greatest unbiased maker of HDD platters, it is critical to retain near relationship with all makers of really hard drives. Today the bulk of SDK’s shipments are platters intended for PMR and SMR HDDs, but it is also ramping up generation of media for Toshiba’s MAMR-dependent drives. The pact with Seagate assures that Showa Denko will also be a section of forthcoming HAMR HDDs.
