Answer 1

Head Nicam Hi Fi Stereo

The is the number of rollers that are used to read the VHS tape. NICAM VCRs have stereo recording systems where high quality audio signals are effectively ‘buried’ beneath the video tracks by an extra pair of recording heads on the spinning tape head drum. This technique is known as DFM stereo or ‘depth frequency multiplexing’. Hi-Fi stereo is in addition to the low-quality mono linear soundtrack, which is part and parcel of the VHS specification
