Multilayered Discs TRIZ Cases
- ECC Encoding Structure for Multi-Layer Disc Compatibility Control
Encrypting data between two ECC stages makes new multi-layer disc data uncorrectable by legacy players, preventing read/write errors.
- Dual ECC Encryption for Multi-Layer Disc Compatibility
Dual ECC encoding around encryption blocks legacy drives from misreading new multi-layer discs and protects data integrity.
- Alternating Pt/Co Regions in Magnetic Recording Media
Alternating magnetic regions with varied Pt/Co ratios and thicknesses ease magnetization reversal while supporting density and thermal stability.
- Magnetic Recording Medium Multilayer Exchange Coupling
An exchange layer couples storage and surface recording layers, transferring magnetization to resolve signal-to-noise ratio issues in volume recording.
- Multilayer Optical Disc Address Offset for Layer Shift Compensation
A multilayer optical disc defines predetermined positional relationships between recording layers to enable continuous data writing.
- Optical Disc Flag Area for High-Speed Lead-Out Recording
An edge portion flag area indicates pre-recorded synchronization data, reducing finalize processing time while maintaining ROM disc compatibility.
- Optical Disc Address Format for Capacity Expansion
A segmented address format expands recording capacity beyond 16.7 GB while maintaining compatibility with existing hardware.
- Dedicated Servo Layer for Continuous Head Position Tracking
A dedicated servo layer provides continuous position feedback via distinct tracks carrying predetermined frequency signals.
- DVD Management Area Identification for Finalize Time Reduction
Management area identification information allows the recording apparatus to recognize embossed pits and omit RF searches, reducing finalize process time.
- De-icing Multilayer Optical Discs via Partial Dummy Data Writing
A formatting method writes dummy data on specific layers of multilayer optical discs to create de-iced areas opposite user data.
- Dual-Layer Disc Guard Track Zone and ECC Interleaving
Segmenting the data area into zones with interleaved ECC blocks preserves PCA capacity while minimizing interlayer crosstalk in dual-layer discs.
