這個網頁給Philips CDM0, CDM1的標題是: When CD was introduced around 1982, Philips’ CDM transports were made extremely well, to the point of being almost over-engineered
簡單來說,菲力浦的cdm0有single-beam(日本sony是3-beam) swing arm (日本sony是直線軌道)system、德國Rodenstock(成立於1877年,是德國研發鏡片長達143年的品牌)玻璃鏡片,cast-iron(鑄鐵)機構(cdm1改成壓鑄鋅),這些在在都是經典設計,符合"over-engineered"誇張一點的形容。
