15、ng Precautions For Traverse Deck The laser diode in the traverse deck (optical pickup) may break down due to potential difference caused by static electricity of clothesorhumanbody.So,becarefulofelectrostatic breakdown during repair of the traverse deck (optical pickup). Handling of traverse deck (o

16、ptical pickup) 1. Do not subject the traverse deck (optical pickup) to static electricity as it is extremely sensitive to electrical shock. 2. To prevent the breakdown of the laser diode, an antistatic shorting pin is inserted into the flexible board (FFC board). 3. Take care not to apply excessive

17、stress to the flexible board (FFC board). When removing or connecting the short pin, finish the job in as short time as possible. (Fig 6.1) 4. Donotturnthevariableresistor(laserpower adjustment). It has already been adjusted. Grounding for electrostatic breakdown prevention 1. Human body grounding (

18、Fig 6.2) Use the anti-static wrist strap to discharge the static electricity from your body. 2. Work table grounding. (Fig 6.2) Put a conductive material (sheet) or steel sheet on the area where the traverse deck (optical pickup) is place, and ground the sheet. Caution: The static electricity of you

19、r clothes will not be grounded through the wrist strap. So, take care not to let your clothes touch the traverse deck (optical pickup). Caution when replacing the Traverse Deck The traverse deck has a short point shorted with solder to protect the laser diode against electrostatics breakdown. Be sur

What is HighMAT? This

22、word combines the abbreviations of Matsushita Electric Industrial Co., Ltd. and High Performance Media Access Technology, and is a trademark of Microsoft Corporation. The products with the HighMAT logo shown below are made according to theHighMAT standard. HighMat is a format that allows users to sa

23、ve digital contents such as photographs, audio and images on a CD. This gives consistency in the way of reading data when general consumer products (such as DVD players) and PCs are used, and thus, it iseasy to operate for the user. 10.2. Why use HighMAT? Up to now, there was no harmonized standard

24、from playing digital content stored in CD-ROM formats (including CD-R) on consumer products like DVD players. Therefore, we used to have problems such as follow: There was no common play list or attached information on contents, which is called metadata. The data compression method differed accordin

25、g to the equipment. As the number of CD-ROMs recorded increased retrieved the contents became more difficult. Because display and operation methods were different depending on the equipment, the play order of the content on the same disc could change. 10.3. The advantages of using HighMAT Applying t

26、he HighMAT standard will solve the following problems and will improve usability. It will create a common user interface for both PC and consumer products. 14 SA-PM29E / SA-PM29EB / SA-PM29EG Regardless of the types of consumer products, such as DVD players, portable CD players, car stereos and mini

27、computers, a consistent way to play for digital content will be created, and it will make it easier to retrieve data. You can also play digital content on the disc, which was created in accordance with the HighMAT format with a conventional CD-ROM player. 10.4. Outline of the HighMAT standard 1. Rec
