Marvell Announces the World's First Read Channel Physical Layer Device to Support Perpendicular Recording

10/1/2002 - Marvell®, a technology leader in the development of extreme broadband communications solutions, announced the industry's first mixed-signal read channel physical layer (PHY) device to support signal equalization and Digital Signal Processing (DSP) features required for perpendicular recording. The new Marvell 88C5575 family of read channel PHY devices, when combined with recording heads and disks designed for perpendicular recording applications, allows customers to pack data bits on magnetic media much closer together than traditional longitudinal magnetic recording techniques.

"Perpendicular recording is widely viewed as the next technology required to continue the magnetic storage industry's astounding achievements in storage density growth," stated Dr. Alan Armstrong, Marvell's Vice President of Marketing for the Storage Business Group. "Next-generation storage products will require higher storage densities, and the perpendicular recording technology in Marvell's 88C5575 family of read channel products will enable storage manufacturers to develop these products."

The 88C5575 product has been developed in collaboration with Marvell and its strategic partner, Hitachi Ltd. "During the development of the 88C5575 read channel device, Marvell benefited from the drive expertise of Hitachi Ltd.'s Data Storage Systems Division. Furthermore, we had the opportunity to learn the latest developments in perpendicular recording technology from world-class research conducted in Hitachi's Central Research Laboratory," added Dr. Armstrong.

"Hitachi believes perpendicular recording is a key technological advancement for future storage systems," said Dr. Yoshihiro Shiroishi at Hitachi Ltd.'s Data Storage Systems Division. "For over four years, Marvell's solutions have helped Hitachi achieve record-breaking areal densities in our storage devices, and the Marvell 88C5575 read channel, which was developed in cooperation with perpendicular recording research at Hitachi's Central Research Laboratory, enables us to continue this trend."

The Marvell 88C5575 read channel incorporates several new advanced features that allow storage manufacturers to reduce costs and time-to-market:

Self-Servo-Write Support
The Marvell 88C5575 read channel incorporates revolutionary Self-Servo-Write technology, which enables the disk drive to write its own servo patterns on the disks during initial manufacturing steps, allowing storage manufacturers to eliminate future capital equipment expenditures for costly servo track writers and to free-up clean-room floor space.

10-Bit Data Encoding
The 88C5575 family includes support for newly developed 10-bit data encoding. Combined with Marvell's highly advanced, industry-leading error correction code (ECC) engine, 10-bit encoding provides significant improvement in error detection and correction capability of the system.

Target MorphingTM Technology
The introduction of the 88C5575 device marks the second generation of Marvell's programmable target architecture. For storage OEMs, this technology enables increased head yields in manufacturing. As storage capacities continue to increase and push the limits of head technology, Marvell's Target MorphingTM technology can be critical to the cost-effective manufacturing of storage devices.
