Memory-Tech has
developed a new measurement system for HD DVD for mass-production lines
at media manufacturers. Due to be available during second half of June
2005, they hope to help promote the HD DVD format by distributing
the disc measurement system.
measurement system supports HD DVD-ROM Book 1.1 specifications for playback-only media. The system can measure the following items, for example: PRSNR, SbER index for HD DVD disc formats, modulation depths, jitters of signals within a lead-in area, the thickness of middle layers bonded between two disc substrates, and tracking error signal levels. The system is also capable of decoding burst cutting area (BCA) data and measuring PI errors. The measurement system can store a maximum of four HD DVD players, and operate them simultaneously. To enable intuitive measurement, the system has capabilities of determining whether an object is "a fine product" or "an inferior product" by matching its measurement results with preset parameters, and mapping the precise location of defects on the disc, for example. |
