This is the Canon MV940 MiniDV camcorder. This is the highest spec model in this formfactor. The MV940 is also the only model that supports DV/FireWire 400 Input. Many manufacturers sold units within Europe that lacked this capability as it would have attracted higher taxes due to them being classed as video recording equipment.

MiniDV is part of the DV (Digital Video) video storage format. It was released in 1995. There are 3 DV cassettes, with MiniDV being the smallest.

MiniDV was the first mass-consumer digital recording format.

Here are some facts:

1) The most popular camcorder storage prior to this was VHS-C (the last analogue format that was widely adopted).

2) MiniDV was replaced by 8 cm DVD +/- R camcorders, later with solid state ones.

3) Data is recorded helical on the tape, i.e. just like VHS.

4) Tape speed is constant 18.8  mm/s

5) DV Resolution is 720 x 480 (DVD standard)

6) Audio can be stored as:
16-bit Linear PCM stereo at 48 kHz sampling rate (768 kbit/s per channel, 1.5 Mbit/s stereo), or four nonlinear 12-bit PCM channels at 32 kHz sampling rate (384 kbit/s per channel, 1.5 MBit/s for four channels)

Audio is stored lossless.

7) Video data bit rate is 25 Mbps. By contrast a modern 4K HDR movie takes ~10 Mbps or less.

Video is stored with lossy compression.

8) All MiniDV tapes are 60 mins long (Standard Play) or 90 mins long (Long Play)

9) Only Sony and Panasonic made them. Sony uses wet lubricant while Panasonic solid. Other brands such as TDK, JVC etc. are re-branded Panasonics.

10) There were no real consumer MiniDV player decks for homes. The camcorders had to be hooked up to TV via composite Video.

11) This pre-dates modern tech such as solid state flash storage, HDMI, etc.

12) Almost all MiniDV Camcorders also have a FireWire 400 port for connecting to another camcorder for tape duplication, or to a PC.

13) Sony made a smaller format called Micro MV which is significantly smaller but the camcorders are very expensive even today.

14) Later MiniDV Camcorders had memory card slots (SD, MMC or Memory Stick) and USB ports, however these were only used for still photography.
