Philips CDM12.1 & VAM1252 | Top
The first Philips 3-beam linear tracking drive mechanism used by Marantz was the Philips CDM12.1. The Philips VAM1252, equipped with a die-cast body and commonly know as the CD Pro, was employed in the high-en Marantz CD-7. The low cost Philips VAM12 version of the Philips VAM1252 was used in the Marantz CD-17Da and Marantz CD-19a. The Philips VAM2200 series, which may be the last Philips-made CD-only drive mechanism, was used in the laters Marantsz CD-only player, the Marantz CD-7300 (2002).
看來說 vam 比較低是因為 vam 12 吧.

我的想法是 cdm 其實是指光頭的 一part, 不包括那金屬板及以下的防震. vam 就是成 set pick up了. 不過我不知道真正是如何. |
