Seagate today authorized a contract with Showa Denko in a quote to safeguard a 2nd resource of plates for its disk drives based upon warmth aided magnetic recording (HAMR) modern technology. Under the regards to the offer, Seagate will certainly assess SDK’s existing products for HAMR media and also both business will collectively create future products.
Seagate began to deliver its Exos HDDs including HAMR inside its Lyve storage space systems late in 2015. These disk drives utilize essential elements, such as tape-recording heads with a close to area transducer that warms up the media along with glass plates with an FePt magnetic layer, established and also made totally internal. Being an up and down incorporated business, Seagate has adequate manufacturing capabilities to proceed constructing plates for HAMR drives inside, however having a 2nd resource for a most importantly crucial element makes a great deal of feeling for high-volume items.
Having actually invested over one decade on HAMR pathfinding and also research study, Showa Denko officially started to create its glass plates for HAMR HDDs in February, 2020. At that time, the business claimed that HAMR would certainly attain areal thickness of 5-6 Tb/in2 in the future, allowing 3.5-inch disk drives with 8 or 9 plates to keep 70 TB – 80 TB of information.
Now, Showa Denko has actually completed growth of its very first HAMR media product including a FePt magnetic alloy and also modern technology to manufacture disk drive plates. Under the regards to the contract in between SDK and also Seagate, the disk drive manufacturer will certainly assess the product made by the Japanese business. Moving forward, Seagate and also SDK will collectively create brand-new magnetic alloys for HAMR HDDs.
In the meantime, Seagate will certainly proceed utilizing its very own FePt glass media inside its HAMR HDDs, however if it discovers Showa Denko’s HAMR media sufficient, it could utilize it for future disk drives.
The agreement in between Seagate and also Showa Denko makes sure that the disk drive manufacturer will certainly have 2 resources of HAMR plates in the future, which will certainly be essential if Seagate substantially increases use of its HAMR modern technology. As a matter of fact, as soon as HAMR media strikes specific areal thickness (i.e., substantially greater than PMR’s 1.14 Tb/inch2), it will certainly make an excellent feeling to take on the modern technology neither just for highest-capacity HDDs, however likewise for midrange HDDs to reduce their prices.
“[HAMR] is not just concerning the greatest capability factor,” claimed David Mosley, Chief Executive Officer of Seagate, at a seminar in 2015. “If we can conserve a disk and also 2 heads in a 16 TB drive, we will certainly take a look at doing that also. So, it is truly throughout the entire profile, which is why we assume that this system play is so crucial. We can present HAMR right into the exact same system. The boost are truly small.”
In addition, Seagate will certainly likewise guarantee that SDK-made HAMR plates will certainly work with its HAMR application, which could end up being the business’s affordable benefit versus Toshiba and also Western Digital once they embrace this modern technology.
“We anticipate this partnership will certainly better increase technical growth originated by the 2 business,” a declaration by Showa Denko reviews.
For Showa Denko, the globe’s biggest independent manufacturer of HDD plates, it is necessary to preserve close connection with all manufacturers of disk drives. Nowadays the mass of SDK’s deliveries are plates made for PMR and also SMR HDDs, however it is likewise increase manufacturing of media for Toshiba’s MAMR-based drives. The deal with Seagate makes sure that Showa Denko will certainly likewise belong of upcoming HAMR HDDs.
