Hello again Folks.

The trouble with having an enquiring mind is that one finds everything fascinating, and collectable.

Over the years, I have owned, used, and repaired a number of camcorders. The newest members of my collection of camcorders are Sony camcorders using the Micro MV format.

The larger is the DCR-IP220E, and the smaller of the two is the model DCR-IP55E.
The Micro MV tape is the smallest video cassette tape ever used in a domestic camcorder.

As can be seen in the photographs, the cassette is narrower than, two, one dollar coins, placed side by side, and is smaller than a “Micro cassette,” as used in telephone answering machines and personal note takers. Both camcorders can also record to memory sticks.

Tape transport functions are accessed via the use of a stylus onto the touch screen monitor.

Information on the standard is difficult to find. The tape speed is about 5.66mm/second.
The head drum is tiny, I don't know its diameter.

Just a personal note. For those of you who still have their parents around, interview them with a camcorder while you still can. Fortunately, I did so in 2005.
