We chose the TA720 Time Interval Analyzer for its high sampling speed and intersymbol interference analysis functions. The playback and recording speeds of CDs and DVDs gets faster with every new generation of products, so we needed a time interval analyzer with a sampling speed that could keep space. Also, thanks to its intersymbol analysis functions, we can measure, even at high recording speeds, the length of the spaces occurring after marks as well as the effects of the interference from those spaces. When we set the widths of the marks and evaluate the recording performance, we use the intersymbol analysis function to measure the jitter distribution of binary signals. Evaluation of recorded disks during the development stage involves establishing recording conditions by using the TA720 to confirm waveforms during magnetic recording. The final evaluation is done on an evaluation tester, and this setup has shortened our development times and given us improved efficiency overall. The TA can display both marks and spaces, so it's very easy for us to visually compare the relationship between the two. For disk rotation jitter analysis, we use the TA720 with its high speed and ability to take a large number of samples.

Media Tek Inc. - Hsin-Chu City Taiwan

MediaTek Incorporated is a dynamic fabless IC company. Since its establishment in 1997, MediaTek has dedicated substantial resources to research and development of comprehensive digital media integrated chipset solutions. MediaTek has now become one of the world's largest fabless IC companies.

Currently, MediaTek's IC products that are on offer include chipsets for CD-ROM, DVD-ROM, CD-R/RW and DVD- R/RW drives for PCs and other consumer products such as DVD players and DVD recorders.

Testing and measuring instruments are very important tool used by engineers to develop optical storage devices. They must be highly accurate and stable, and match the special conditions of our experiments. Each R&D engineer has one set of measuring instruments, and in order to obtain identical results for all experiments, R&D groups must be very careful to choose measuring instruments of excellent quality.

In the photographs below, we are using the TA720 Time Interval Analyzer to perform analysis of jitter and inter symbol interference. The Yokogawa TA720 is alo an excellent instrument for this application.

LG Electronics Inc.

LG Electronics focuses mainly on the three areas of optical storage, digital AV, and mobile internet appliances, and is working hard to improve its technology and product development capabilities. In particular, LG's level of technology in the area of optical storage has become very high during the past several years, and we are now using that technology to design and manufacture world-leading products. Recently, our company debuted the Super-Multi DVD Writer (model GSA-4040B) which is the first such device in the world that can support the DVD-RAM, -RW, and +RW formats. The Super-Multi DVD Writer allows users to freely play back, record, and edit large quantities of data on a DVD, which holds  Tm Testimo 03

Yokogawa has a very close relationship with LG, and supplied us with high quality measuring equipment which became very popular and trusted tools in both our R&D department and manufacturing lines. For our digital display and media products, we are using ten of the TA520 /TA720 Time Interval Analyzers, and eighty of the DL7440/DL7480 , DL1740, and DL1620 Digital Oscilloscopes. For digital appliances, we have brought in two hundred of the WT series power meters, and about one hundred of the Darwin series of hybrid recorders.
