Disc-Shaped Record Carriers TRIZ Cases
- Optical Disc Spare Area Status Updates for Accurate Defect Lists
Updating spare-area block status when capacity changes keeps defect lists accurate and avoids unnecessary optical drive operations.
- Disk Drive Self-Diagnosis for Manufacturing Rack Failure Detection
Built-in monitoring of power supply and spindle rotation detects rack-unit faults during disk drive manufacturing without extra inspection equipment.
- Optical Disc Defect Mapping Using ECC Error Thresholds
ECC block error counting and threshold comparison pinpoint defective disc areas, enabling targeted rewriting and stronger data resilience.
