Big Data and Cloud Storage -- A Recording Head Perspective - Herbert Lin

  1. 1. Big Data and Cloud Storage--- A Recording Head PerspectiveHerbert LinVP, Heads R&D, Western Digital ®
  2. 2. Ubiquitous Data Needs --- A Personal ReflectionLast week while vacationing inHawaii, we stayed in an off thegrid tree house in the middle oftropical forest Access by dirt road Solar power Rain water collection Recycled material + tree branches No Phone/Cable/Internet The owner plans to increase his online storage due to his expanded business ® WD Confidential
  3. 3. Fun Facts About HeadsSmall A 6” wafer has ~ 50,000 Devices A slider weights ~ 0.6 mg Critical dimensions smaller than semi-conductorCritical Provide write and read functionComplicated > 60 layer of Masks > 800 critical wafer process stepsVulnerable ~ 60 miles/hour ~ 2 nm of clearance Equivalent to flying from San Francisco to New York (>4000km) at a height of ~30 mm No birds in the air, no trees on the ground, no waves over any water, no houses, no mountains ® WD Confidential

  5. 5. Heat Assisted Magnetic Recording (HAMR) Next major technology for AD extendibility with minimal system impacts. Heat Assisted Magnetic Recording uses continuous recording media which has good thermal stability at room temperature To record on this type of media we must first heat the media until it becomes writeable with conventional recording fields Other forms of energy assist are ® also being explored WD Confidential
  6. 6. Critical Dimension Trend Challenges: HDD is on a steeper slope for CD (critical dimension) shrinkage Opportunities: Introduction of new cost effective equipment for storage industry ® WD Confidential
  7. 7. Wafer Mask Layer Increases AD growth requirements continuously drive wafer process complexity on the same magnitude as semiconductor industry ® WD Confidential
  8. 8. Development Cycle and Capital Investment • Long Cycle time AD Growth >30% • Code ---- Days HAMR needs to launch • Disk ---- Weeks • Head --- Months • High CapEx AD Growth Slows More heads/disks per HDD More Capex $$ ® WD Confidential
  9. 9. SummaryStorage demand is ubiquitous Off-the-grid does not equate off-the-cloudMagnetic head technology has been and will continue tobe a key driver to sustained growth Next technology is Heat (Energy) assistedLeading edge process complexity will continue to be atrademark of head development Critical talent is more important than everDevelopment cycle time and intensive capital investmentrequire critical business decision-making ® WD Confidential
