ASTC Can Help Address HDD Technology Challenges • HDD Industry is facing challenges to grow areal density at historic rates • These challenges are distributed throughout component and system level technologies • Energy assist technology will not in itself enable AD growth without adequate readers, H/M interface, channel, servo capability, etc. • Solid State Technology has emerged as a credible alternative to HDD in certain segments, and the semiconductor industry is committed to large scale R&D • ASTC provides the ideal forum to address these challenges collaboratively as an industry with a holistic but targeted approach
Signal Processing Contribution to HDD Density Growth Single par?cle super paramagne?c limit (es?mated) 55 Tb/in 2 14 Tb/in 2 3 Tb/in 2 LDPC Charap’s limit (broken) Son ECC 10‐bit RS SPC Programmable target PRML
Recent Trends in Signal Processing • SNR improvements coming from the Read Channel (RDC) were driven by advancements in Error Correction Coding (ECC): large codeword size afforded by adaptation of Long Sector Format, and transition to Soft ECC • Shingled recording, Bit Pattern Recording (BPR), Two-Dimensional Magnetic Recording (TDMR), and Heat Assisted Magnetic Recording (HAMR) provide new challenges to signal processing • Hard disk controller SOC should no longer be viewed as a standalone component in the drive; it has become an integral part of system solution.
Challenges Going Forward • HDD is facing severe compe??on from SSD and other storage technologies • HDD industry needs to collaborate to define a technology roadmap • A roadmap gives our industry more nego?a?on power with customers • New technologies require more R&D investment and collabora?on • Peak detectors have long been replaced by PRML with sophis?cated detectors designed to take signal characteris?cs into account • Powerful itera?ve decoders come to replace tradi?onal algebraic ECC’s • Culng‐edge CMOS technology in electronics design is key to future success. • Leveraging some technologies used in solid state drives in support of large block write formats in SMR • Adding some level of non‐vola?le chip memory support for power‐loss handling
Why is the HDD supply base interested in ASTC?
Suppliers meet HDD Factories • HDD producers operates at the outer boundaries of technology & scien?fic knowledge • “There’s plenty of room at the boKom” § • One nanometer is the characteris2c dimension • substrate processes, spuKering, chemistry, metrology • Two million hours is the characteris2c MTBF • automa?on, disk processing systems, cleaning, RV • Three gigahertz is the characteris2c frequency • SOC, control, interface • Suppliers must meet producers needs at the outer boundaries of technology & scien?fic knowledge § Richard P. Feynman, 29 December 1959 26
Suppliers to HDD Producers • Far‐flung supply chain provides materials, components, manufacturing, processing, and test equipment: • substrates • magnetic metrology • specialty metals • optical metrology • sputtering systems • chemicals • automation • suspensions • cleaning systems • pre-amps • processing equipment • channels • processing supplies • SOC’s • certification • servo track writers • dimensional metrology • Supply Chain Goes On ... 27
