The HR-C3 was the first true VHS-C machine, using a miniaturised mechanism. The C3 is a very neat unit, surprisingly sophisticated and modern-looking for its age, with LCD displays and touch-sensitive buttons.
All the controls and connecting sockets are on the top of the machine, and a neat sliding flap covers and protects the playback controls while the camera is being used to control it. The well-designed carrying case allows access to all controls, sockets and - most importantly - the battery, which clips to the bottom of the deck.

Unlike many full-size portables, no power is required to load or eject the tape, and there is a another clever battery-saving feature which powers down the machine between recordings, without unlacing the tape. This allowed shooting to continue later, without introducing noise or picture disturbance at the start of the next shot; most other machines could only guarantee this if the machine was left on between shots.
A tuner was also available to go with the machine, but timed recordings were not possible - VHS-C was not meant to be a home deck format.
In order to make the machines as small as possible, a reduced-sized head drum was used, 41mm rather than full-sized VHS's 62mm. To keep the recorded signals compatible with VHS, four heads were used, with the tape wrapped three-quarters of the way around the drum, and the drum spinning at 1.5 times normal speed (2250 RPM rather than 1500). The four heads take turns writing: as head 1 completes its scan, head 2 has travelled 3/4 of the way around and so is ready to start the next field.
This reduced-sized mechanism allowed the HR-C3 to be extremely small, about 20cm square, and kept the weight down to a remarkable 1.9kg.
