> SECTION 02: APPLICATION PROTOCOL (SOP-01)

--------------------------------------------------------------------------------

[STEP 1] Inspect substrate under high-CRI light for deep physical fractures.

[STEP 2] Apply 1 to 2 drops of SPECTRA N:1.58 formulation onto readable side.

[STEP 3] Distribute RADIALLY from center to outer edge using microfiber weave.

CRITICAL: Never wipe in circular motions. Preserve tracking pits.

[STEP 4] Allow optical equilibrium (30 seconds) before insertion.

--------------------------------------------------------------------------------

Q: WHAT IS SPECTRA N:1.58?

A: An optical-grade substrate preservation fluid formulated to match the refractive index (n ≈ 1.58) of compact disc media, minimizing laser scattering and CIRC error correction overhead.

Q: WHY AVOID ISOPROPYL ALCOHOL (IPA)?

A: IPA and domestic cleaners induce micro-crazing and progressive clouding in optical polycarbonate over time, risks edge-seal penetration, and causes laser rot on aluminum/gold reflective layers.

Q: HOW DOES IT AFFECT HIGH-FIDELITY PLAYBACK?

A: By matching the optical index across surface micro-scratches, the 780nm laser beam avoids refraction drift. Results in a cleaner RF eye-pattern, reduced digital jitter, and restored phase linearity.

Q: SYSTEM COMPATIBILITY?

A: Designed for non-oversampling and multi-bit DAC architectures (Philips TDA1540 / TDA1541 as reference standard) and swing-arm optical transports (CDM-0, CDM-1, CDM-9 as reference standard).
