High-Definition Media Process Authoring Mastering Galvanic Replication Printing Packaging Content Tracker – DiscTag – BCA - ROM MARK Ident Code & Print Inspection Electrical & Mechanical Testing Master Disc Stamper CoverTest Final Inspection “check” RECORDING PLAYABILITY PLAYABILITY

Universal Stamper Checker (TS) • Physical check “full scan” of CD/DVD/BD stamper in less than 2 minutes: ▫ Roughness ▫ Thickness ▫ Flatness ▫ Cosmetic defects

Replication - Printing Balance Analyzer Mk. 2 • Unbalance is caused by molding and/or print • can lead to “playability” issues Balance Analyzer Mk. 2 • All discs formats covered • Stand-alone unit • Results delivery in less than 10 sec. • Not sensitive to external vibrations • Shows vector of unbalance

Challenge of electrical Disc Testing 1. Laser Spot Quality Important: Spot out of focus • High Quality Optics • Mechanical stability Focused spot • Reference Discs 130 µm • Reference Devices 2. Mechanical conditions of drives • Stable environment “Test Time”

Optical Media E arly W arning S ystem • Scan of discs can be done in less than 10 min (depends on the disc format) • Fully integrated PC with Video Playback function • Write Recordable Reference Discs and make full tests afterwards • DVD & BD Read/Write in one Drive • available as IN-line and OFF-line desktop system • Multiple Test Function

Supported Formats: BD-ROM Single/Double Layer BD-R Single/Double Layer BD-RE Single/Double Layer DVD ROM Single/Double Layer DVD-R / DVD+R Single/Double Layer DVD-RW / DVD+RW Single/Double Layer DVD+RAM Single/Double Layer Read Speed: individual selectable 1x/2x/4x/8x/16x BD up to 8x DVD up to 16x Write Speed: individual selectable BD 1x/2x/4x/8x DVD 1x/2x/4x/8x/16x Measured signals: (not Spec compliant) BD Jitter, LDC, BIS DVD Jitter, PIE, PIF, FE, TE

EWS DVD/BD drive “selection” • Key to have reproduceable results • Standardized tests to find out GOOD drives • Parameters of interest  time for the standard tests  LDC value (Long Distance Code) number of parity errors on LDC codeword's per ECC block  BIS (Best Indication Subcode) number of parity errors on BIS codeword's per ECC block  Behavior of the drive at a known defect  Jitter value (raw with no compensation)

Optical Media E arly W arning S ystem • Drive selection - LDC diagram At the known defect the drive reduces the rotation speed, therefore the read out rate drops down. Read out at 1x The LDC value shows the maximum value. After the defect the LDC value recovers. GOOD drive

Optical Media E arly W arning S ystem • Drive selection - LDC diagram At the known defect the drive reduces the rotation speed The LDC value shows the maximum Read out at 1x value. After the defect the LDC value does not recover. BAD drive

Optical Media E arly W arning S ystem • Drive selection - Elapsed test time The detail table shows 2 different tests performed on 4 drives. The yellow highlighted values show different elapsed times compared to the results of drive 2-4. Drive1 BAD

Optical Media E arly W arning S ystem • Max Read Speed of 8X Increasing read speed Constant rotating speed • The hardware limit is 3,4X. The drive starts to rotate with 3,4X at radius of 24mm and keeps it constant over the whole disc CAV-constant angular velocity • The perimeter (s=2 r) at radius 24 is 150,8mm, at radius 58 it is 364,4mm • This is 2,41 times longer than inside multiply by 3,4 we get the max Read speed of 8X
