From Pathfinder Wiki
The magnetic tape on VHS-C cassettes is wound on one main spool and used a sort of a gear wheel which moves the tape forward. It can also be moved by hand and so is the spool. This development hampered the sales of the Betamax system somewhat, because the Betamax cassette geometry prevented a similar development.
