7 Today s Menu! HDD Integration by Design Studio 今天的議程! 硬碟整合 Acoustic Vibration Mounting Shock Temperature 1 Integration item 整合項目 Consideration Factor 考慮因素 Mounting Design S-ATA Quality Performance Interface FPC Design Write Cache Data Block Size P-ATA CE-ATA BIOS / FS Power and Heat FPC Recommendations for Z.I.F. Small HDD Interface (CE-ATA)

8 HDD Operation 硬碟的運作

9 Head Fly Height 磁頭飛行高度

10 Mikey Snubber Design Mikey 減震材質設計 Recommended Snubber ( No Screw Hole or Guide Rail ) Design TGT : Drop against Hard floor > 120 cm (Embedded into a Product, like MP3 Music Player)

11 Free Drop Models ( w/ Snubber ) 自由跌落模型 ( 含减震材质 ) Free Drop Models - Reality is somewhere between two models Ideal Damper Model Optimistic Sway Length (mm) drop height (m) Linear Spring Model Pessimistic Sway Length (mm) drop height (m) > 2000 G G G < 300G fatal damage fatal damage / saved by free drop sensor media defect / saved by free drop sensor no error

12 Head Unload Time 讀寫頭歸位時間 Drop Height and Faling Time by Gravity Falling Time[msec] By Standby Immediate Command By Unload Immediate Comman Drop Height[cm] Emergency Unload by Power Off

13 Typical Failure Mode : Free Drop 典型錯誤模式 : 自由落下 Conclusion: Disk Shift by external mechanical shock FA result: Power-on Ready fail with seek retry-retry noise observed. Large RRO (Repeatable Run Out) POR fail is due to large RRO, which is occurred by mechanical shock.

14 Typical Mode Frequency ~Disk and Actuator~ 典型頻率模式 ~ 磁碟和磁臂 ~ 1.97kHz 3.17kHz 4.00kHz 3.5kHz (1 st Bending) 6.8kHz (1 st Torsion)

15 Notebook PC Tilt drop test 筆記型電腦傾斜落下測試 SRS (Shock Response Spectrum) analysis comparison Arm bending mode

16 Microdrive Shock Robustness 微型硬碟撞擊能力 Low Effective Mass (Facing DE base plate) Effective Mass x G (Shock) < Gramloa

18 Magnetic Field and Mechanical Scaling 磁頭與機構的小型化 Shrink everything Requires vastly improved processes Higher mechanical precision Magnetic Scaling Enables mechanical scaling Lower cost per bit Higher performance Higher capacity in smaller form factor Mechanical Scaling Lower Power Faster Move time Higher Resonant freq. All scale favorably (with length or better)

19 Achieving objectives for : past, present, & future 過去現在與未來

20 HDD Data Transfer Rate 硬碟資料傳輸速率 Media Data Rate vs. Interface Transfer Rate Media Data Rate Sustained rate at 757 Mb/S Read/Write Cache or Electronics Data Buffer ATA Interface Data Rate Transfer rate 133 MB/S HDD System

21 HDD Performance 硬碟效率 Areal Density Spindle RPM Seek Time Microcode Efficiency Error Recovery # of devices Interface Rate Parameter settings Media Data Rate Servo System

22 Technology Challenges 技術的挑戰與瓶頸

23 Longitudinal vs. Perpendicular 磁頭 : 水平式與垂直式的記錄方式

24 Technology Roadmap 技術的演進 Every 2x in areal density means a new set of challenging technologies Areal Density (Gb/in2) new technologies (MR head, thin film media, PRML) and standardized FF enhanced competition, and new technologies (GMR heads...) advanced longitudinal media 50-60% perpendicular/ tilted media 30-40% thermal assist or patterned media 20-30% Year product available (Mobile)

25 Disk vs Capacity 碟片與容量 Real Estate 70mm DATA ZONE: 106 Φ 25mm Φ 70mm DATA ZONE: " Φ 25mm Φ 84mm LOAD/UNLOAD & PICO SLIDER DATA ZONE: " DATA ZONE: 100 Φ 20mm Φ 65mm DATA ZONE: 57 Φ 12mm Φ 48mm Φ 25mm Φ 95mm DATA ZONE: 13 Φ 7.0mm Φ 27.4mm 2.5" 1.8" 1.0"

26 Electronics Roadmap Host Interface Trend 系統介面技術趨勢

27 HDD into CE Devices? 應用於消費電子産品中的硬碟? MMC or SD Memory already there Memory Interface is not suitable for HDD Write cache, Power saving, SMART.. are out of scope No Error Condition other than Time-out Too tight timeout value for HDD Capacity Limitation : Up to 4GB Max. current limitation ( 100mA for read, 250mA for write )
