A booklet on Audio-Technica MC phono cartridges, focused on the Dual Moving Coil (デュアル・ムービングコイル) technology - separate coils for each stereo channel rather than a single wound coil as in conventional MC designs. Six models from the AT30E at ¥17,000 up to the AT34E II flagship at ¥45,000 with samarium-cobalt magnets, plus two step-up transformers AT650 (¥29,000) and AT630 (¥13,000) for connecting to MM phono inputs.
- デュアル・ムービングコイル - Dual Moving Coil - separate coils for each stereo channel instead of a single shared coil
- サマリウム・コバルト・マグネット - Samarium-cobalt alloy magnets - high magnetic flux density at low weight
- カッターヘッドと相似形 - Cartridge body shaped after the cutting head for accurate groove tracing
