PLAYABILITY

Final Inspection

“check” RECORDING PLAYABILITY

• Physical check “full scan” of CD/DVD/BD stamper in

less than 2 minutes:

▫ Roughness ▫ Thickness ▫ Flatness ▫ Cosmetic defects

Universal Stamper Checker (TS)

• 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

Replication - Printing Balance Analyzer Mk. 2

Challenge of electrical Disc Testing

Focused spot Spot out

• f focus
• 1. Laser Spot Quality

Important:

• High Quality Optics
• Mechanical stability
• Reference Discs
• Reference Devices
• Stable environment
• 2. Mechanical conditions of drives

130 µm

“Test Time”

• 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

Optical Media Early Warning System

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

• n 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 Early Warning System

• Drive selection - LDC diagram

Read out at 1x

At the known defect the drive reduces the rotation speed, therefore the read

• ut rate drops down.

The LDC value shows the maximum

• value. After the defect the LDC value

recovers. GOOD drive

Optical Media Early Warning System

• Drive selection - LDC diagram

Read out at 1x

At the known defect the drive reduces the rotation speed The LDC value shows the maximum

• value. After the defect the LDC value

does not recover. BAD drive

Optical Media Early Warning System

• 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 Early Warning System

• Max Read Speed of 8X

Increasing read 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

Constant rotating speed
