Voluminous global data needs fast, compact and less volatile devices that can reliably accommodate information for decades. Magnetic is the most widely used technology in storage and memory industry.
2014 CEATEC conference was held in Japan recently where the foremost brand of magnetic devices displayed their new leading-edge products.
We will look at the latest technical advancements in the market dominating magnetic devices:
- Hard disk drive HDD
- Backup tapes
TDK engineers have extended the MRAM portfolio to a new state-of-the-art memory chip based on the innovative STT (Spin-transfer torque) technology. This 8MB chip is tested on 8-inch silicon wafer.
TDK’s representatives at 2014 CEATEC conference mentioned that these cutting-edge device will be manufactured by their Headway Technologies. This department is the mastermind of TDK’s HDD head design.
A demonstration was made at the event, and the results showed that data writing speed of traditional flash memory devices was 7 times slower tan STT-MRAM.
Other key players in STT-MRAM and MRAM industry are Crocus and Everspin.
Hard disk drive HDD
New breakthrough technologies displayed at the event were STT (Spin Tunnel Torque) MRAM and HAMR (Heat Assisted Magnetic Recording). Both technologies will help boost the performance, robustness and reliability of hard drives.
TDK representative assured that they would be embed this innovative HAMR functionality in their HDD portfolio featuring 10000 RPM. Addition of this technology will deliver excellent consistency and the users would be able to reliably capture HDD TV recording.
High definition media files will be recorded with exceptional accuracy. These hard drives will have the capability to write 30-hour HD media files each day for five consecutive years. TDK experts predicted that these superior quality drives would be most probably launched in market by the year 2016.
On the other hand, Seagate is considered as the technical leader for this breakthrough HAMR technology. The structure of the HDD will require significant changes which include the drive media and head. Moreover, laser technology will be used to heat the storage disk, head and other components.
Backup Tape Format
IBM, the technical giant in tape storage, announced that its well-renowned 3592 tape format will be extended to 5th generation. This leading-edge system, known as TS1150, will feature:
- Enormous 10 terabyte storage
- Writing speed of 360 Mbps
The earlier version TS1140 has the ability to store data at 250Mbps and record 4TB. Its close rival Oracle T10000C and LTO ultrium 6 can backup 8.5TB and 2.5TB respectively.
LTO consortium has decided to extend its generations to LTO-10, which would be a 48TB media tape. Fuji and IBM are using new tape formulation based on “Barium Ferrite”. Both have demonstrated in their laboratory a massive capacity half-inch tape featuring 154TB storage.
IBM has used Barium Ferrite formulation for its new TS1150 cartridge.
These technical advancements show that the HDD and other storage devices based on magnetic technology still have a long roadmap.
Magnetic storage functionality might be the solid platform for developing volatile memory devices, and a reliable substitute for the traditional DRAM and SDRAM.
