  2. Approach for AV Specification in ATA-HDD GOAL Realization of Compatibility between HDD makers,HDD’s Generations SCOPE AV Specification in ATA-HDD 　：　① and ② Area ATA-HDD Standard Spec Examination for AV Specification 　●Performance 　　　・Capacity 　　　・Transfer Rate 　●Reliability 　　　・Error Rate 　　　・Temperature Humidity Vibration Shock 　　　・Life 　●Power consumption ① Additional Spec. ③ ・Examination for AV Stream recording, specially a response dalay caused by Retry,Reallocation → Help by AV Command → Way of describe with AV Stream recording performance Propriarly Specification of each Application ② Modification Spec. Supplement Spec. ・Unification of described Spec. ・Supplementation of Spec. explanation ・Modification of described Spec.

  3. Consumer HDD WG Discussion items 1. AV Command for Table type Command Specification “Limitation of Command Execution time “ ・Desired Function - Limitation of Command execution time - Command abort or Command reset - Simple Handling ・Condition of set up and use - resolution - method of command abort/reset - method of usage ex1: AV R/W command , PC R/W commandco-exist together ex2. AV R/W command only exist after parameter set up ex.3 AV R/W mode, PC R/W mode exclusively exist ・Definition of an exception matter 2. Reliability ・Temperature , Humidity , noise , SMART , Vibration/Shock Characteristics of Electronics ・Frequency table with the response time of every recording unit 　　　→　method of measurement of , data compatibility

  4. Response Items

  5. Reliability Items (1)

  6. Reliability Items (2)

  7. Frequency table with the response time of every recording unit • Purpose • Evaluation for HDD’s continuous recording ability • of AV Stream • Methods • - Measurement of Recording or reproducing time • in every Recording units • - Recording unit size ex.256～1MByte • - Condition • ex. Cash ON • Retrydefault • SMART OFF • Reallocation OFF • - way of measurement • >sequential write or read the Recording unit • >measurement of response time • >make Frequency table
