Cassette deck Technics RS-TR355
I'm still looking for experiences with this deck as well as other types!

About the technology of cassette decks

General things:

Stereo double cassette deck with 2 one-engine drives.
Recording on deck 2 only, deck 1 can just play back.
Has Dolby® B and C noise reduction and HX PRO.
Connection is via cinch cables; headphone jack without volume control.
Separate (!) level controls L/R (a bit clumsy).
Features auto-reverse and can record on Type IV (metal) tapes.
The equalization is set according to the indexing holes (see bottom of page).
Unfortunately no external bias control (at least you needn't care about it).
Level meter can be switched from -20...+6dB to -3...+8dB in 1dB steps.
Supports high speed dubbing (dubbing with twice the normal speed).
Rewinding time for a C-60 cassette: about 105 s
Technical Data 
(adapted from the manual)
Bias frequency 80 kHz
Tape speed 4,76 cm/s (1-7/8 in/s) or 9,53 cm/s ( 3-3/4 in/s) during high speed dubbing
Wow and flutter 0,07% (WRMS) or 0,2% (DIN)
Frequency response (DIN) 

For an explanation of the formulas, see next chart. 

Fe2O3 20Hz-17kHz
CrO2 20Hz-17kHz
Fe 20Hz-18kHz
Input sensitivity / impedance 60mV at 47kOhms
Output voltage / impedance
Cinch:  400mV at 800 Ohms
Headphones: 30mV at 8 Ohms
(impedance of phones 8 - 600Ohms)
Overview of indexing holes
Type of cassette Number of indexing holes Position on cassette
Ferric oxide (Fe2O3) none, only write protection none
Chromium dioxide (CrO2) 2 next to write protection
Metal (Fe) 4 2 next to write prot. + 2 in the middle (see fig.1)
