Nakamichi CR-40
Documentation on the Nakamichi CR-40 is thin. What the record shows is a single-speed cassette deck — 4.8 cm/s, 4-track, 2-channel stereo — with a DC motor and a frequency response rated at 20 Hz–20 kHz (±3 dB). Wow and flutter is listed at 0.045% (WRMS), with a separate 0.08% (DIN) figure also appearing in the sources; the two numbers reflect different measurement standards rather than a true conflict.
The head configuration is where the record gets genuinely murky. One source describes the CR-40 as a “2-head” deck while also listing one playback, one record, and one erase head — which is internally inconsistent. I’m noting both statements as they appear in the sources rather than guessing which is right. A period listing in HiFI-Stereo (August 1973, p.18) placed the deck among new high-fidelity equipment of the era, though it offered no detailed review of this model.
Known specifications:
- Type: 2-head, single compact cassette deck (as stated in source)

No production years, original price, or further design context have surfaced. If you own a CR-40 or have seen its manual, the Archive would welcome the details.
