Difference between Bottom and Top Tape Heads

While top and bottom tape heads may seem similar at first, this article uncovers the subtle yet crucial differences between them.

Mounting

• Top Tape Head:
  1. Angle the front hook of the tape head first for loading.
  2. Attach the back of the tape head to the shaft and lock it securely.
• Bottom Tape Head:
  1. Attach the front hooks of the tape head into the shaft.
  2. Lay the tape head on the back shaft for mounting.

The top tape head uses a hook to secure itself to the top mask, whereas the bottom tape head relies solely on the shafts for stability.

Orientation

The orientation of each tape head is distinct. The top tape head is in a standard position, while the bottom tape head is mirrored and inverted. Furthermore, the tape in the top head rotates counterclockwise, while the bottom tape rotates clockwise.

Parts

Although many parts are similar or identical, specific components differ between top and bottom tape heads. Notably, the main springs come in different colors: golden for top heads and chrome-colored for bottom heads. This variation is due to the differing exertion forces required, with chrome springs exerting more force to counteract gravity.

This detailed comparison sheds light on the unique characteristics of top and bottom tape heads, offering clarity on mounting processes, orientations, and parts. Should you require further clarification or adjustments, please don't hesitate to reach out.
