Sansung Hard Disk Drive Business is Now Seagate!Seagate and Samsung announced that they have entered into a definitive agreement on April 19,2011 as following:

1. Samsung combining its hard disk drive (HDD) business into Seagate;
2. Extending and enhancing the existing patent cross-license agreement between the companies
3. A NAND flash memory supply agreement. (Samsung will provide Seagate with its market-leading semiconductor products for use in Seagate’s enterprise solid state drives (SSDs), solid state hybrid drives and other products.)
4. A disk drive supply agreement(Seagate will supply hard disk drives to Samsung for PCs, notebooks and consumer electronics.)
5. Expanded cooperation between the companies to co-develop enterprise storage solutions;
6. Samsung receiving significant equity ownership in Seagate;
7. A shareholder agreement under which an executive of Samsung will be nominated to join Seagate’s Board of Directors;

The combined value of these transactions and agreements is approximately $1.375 billion USD, which will be paid by Seagate to Samsung in the form of 50% stock and 50% cash.

These transactions and related strategic agreements will enable both companies to better align their current and future product development efforts and roadmaps, accelerate time-to-market for new products and position the companies to better address rapidly evolving opportunities in markets including, but not limited to, mobile computing, cloud computing and solid state storage. In connection with its strategic alliance with Samsung, Seagate expects also to strengthen its relationship with TDK Corporation/SAE Magnetics (H.K.) Ltd. Together, these transactions and agreements broaden a strategic relationship between Seagate and Samsung that began with a joint development agreement announced in August 2010.

“We are pleased to strengthen our strategic relationship with Samsung in a way that better aligns both companies around technologies and products, with these agreements, we expect to achieve greater scale and deliver a broader range of innovative storage products and solutions to our customers, while facilitating our long-term relationship with Samsung.” – said Steve Luczo, Seagate chairman, president and CEO.

Seagate expects these transactions and agreements to be meaningfully accretive to non-GAAP diluted earnings per share and cash flow within the first full year following the closing, and Seagate does not expect any material restructuring costs in connection with them.

“Delivering value to the market and consumers is the primary goal of the extensive agreement announced today. Samsung looks forward to extending our existing strategic ties with Seagate, to deliver creative technology solutions for a broad diversity of consumer, business and industrial applications,” – said Oh-hyun, Kwon, president of the semiconductor business of Samsung Electronics.

The transactions and agreements significantly expand Seagate’s customer access in China and Southeast Asia. In addition, the mutual supply agreements enable Seagate to secure an important source of leading-edge NAND flash supply as the company expands its SSD and solid state hybrid product offerings, and position Seagate to be a more significant supplier of disk drives to Samsung. The agreement also gives Samsung a significant ownership position in Seagate.

Under the terms of the agreement, Samsung will receive consideration consisting of 50% Seagate ordinary shares and 50% cash. Upon closing, Samsung will receive Seagate ordinary shares valued at $687.5 million (45.2 million shares, or approximately 9.6% ownership of Seagate, which is based on Seagate’s 30-day volume weighted average stock price prior to signing), plus $687.5 million in cash. Samsung will have a right to designate a nominee to j oin Seagate’s Board of Directors following closing.

The agreement has no financing contingencies, and is subject to customary closing conditions, including review by U.S. and international regulators. The transactions are expected to close by the end of calendar year 2011.

Because Hitachi recently transfered its hard disk drive business to Western Digital, the cooperation of Samsung and Seagate is almost inevitable.

Samsung Hard Drive Glossary TOC
Table of Contents

Track
a radial position of heads over the media (circular ring)

Track following servo (also closed loop)
Control system which reflects if the head is in the correct position over the track, if this isn’t the case, the actuator is instructed to adjust its position (in real time)

Transfer rate
the speed at which the drive sends and receives data from the controller

Thin-film head

PRML
Partial-response maximum likelihood. Data is stored on hard drives as a tiny area of magnetism for each bit. As more and more data is squeezed on a disk, the magnetic areas become closer and closer and may affect one another. PMRL is a set of steps applied to data read from the disk. It removes probable errors and produces valid data from the tightly packed bits. PMRL allows an increase of up toe 30 % in the density of data on the disk
