MILPITAS, Calif., Nov. 3 /PRNewswire/ -- Read-Rite Corporation (Nasdaq: RDRT - news) and HMT Technology Corporation (Nasdaq: HMTT - news) today announced that they have achieved a fifth world record in magnetic data storage, demonstrating giant magnetoresistive (GMR) heads at an areal density of 36 billion bits per square inch, or over 50 billion bytes per 3.5 inch platter. This new record represents a 40% increase over the 26.5 billion bits per square inch record reported by the companies only 3 months ago.
This record setting demonstration was accomplished using the high sensitivity Read-Rite dual spin valve trimmed head, HMT advanced low noise, low glide and thermally stable (< 0.5% per decade @ 543KFCI) media produced on NiP coated aluminum substrates, and a trellis-coded noise predictive read channel from Marvell Semiconductor Inc.
''One of the major accomplishments in this demonstration is our ability to achieve 36 billion bits per square inch using independent media and channel suppliers. We believe our system level approach to advanced development is proving to be very successful and is already providing a competitive advantage to our customers,'' said Dr. Subrata Dey, Vice President of Advanced Technologies. ''As we announced in August, we anticipate our innovative design will soon be extended to an areal density of over 40 billion bits per square inch.''
''Elements of this innovative GMR head technology have been integrated into today's products such as those qualifications announced last week for Maxtor, Samsung, Seagate, and Western Digital,'' said Alan S. Lowe, President and Chief Operating Officer. ''In addition to providing a competitive advantage to these customers on their existing products, this advanced technology is providing a benefit on the next generation of products we are now delivering to our customers in connection with new program qualifications.''
''This most recent HMT and Read-Rite milestone highlights the technology leadership capability of both organizations and the availability of such technologically advanced products in the merchant marketplace for our broad customer base. It also bodes well for the ability of the disk drive industry to meet the challenges of more storage intensive applications which require low cost solutions, very high volumetric capacities, and lower component content in the drive itself,'' said Dr. Michael A. Russak, HMT's Vice President of Research and Development and Chief Technical Officer.
''Marvell is pleased to have contributed to Read-Rite's ongoing success in achieving a new areal density record with our 88C4200 PRML read channel'' said Dr. Alan Armstrong, Vice President of Marketing for Marvell's mass storage division. ''The 88C4200, which incorporates our advanced mixed signal DSP technology and trellis-coded noise predictive Viterbi detection, plays a key role in the success of increasing areal densities,'' he added. ''As such, Marvell's commitment is to continue to provide state-of-the-art read channel solutions to meet the industry's ever increasing areal density requirements.''
The companies achieved the areal density of 36 million bits per square inch with linear densities of over 511,000 bits per inch, track densities of over 70,400 tracks per inch and data rates of 173 million bits per second (21.6 million bytes per second). The on-track error rate was less than one error in over a billion bits read with over 22% off-track capability. The heads, incorporating Read-Rite's innovative sensor and writer structures, were manufactured at Read-Rite's production facility in Fremont, California and utilized Read-Rite's advanced pico slider process.
HMT Technology Corporation independently designs, develops, manufactures and markets high-performance thin-film disks.
