Note 2: Explanation of "Tape position" of the Supplementary Data
The Tape position Data is the area data of S-reel that is used for judgment of reducing speed in the Main microprocessor
IC6001, and as the tape position is moved from the starting edge to the finishing edge, the value becomes smaller.
The Tape Data does not become "0" even if the tape reaches the finishing edge as the hub remains, and the tape position
values are different between the large hub and the small hub as the each diameters are different from each other.
60 min. or less type (Large Hub)
90 min. or over type (Small Hub)
l "A" and "E" is hexadecimal. "A" =10 (Decimal), "E" =14 (Decimal).
l Hexadecimal indication from "A" to "E" are shown below.

Tape Type
S-reel pulse is less than 3 when the loading has been completed.
(Miss catching the tape)
Pulse Timer over during the short rewind at the DOWN position.
(Error of S-photo sensor system, S-reel system, Capstan system)
Mechanism lock from the DOWN position to the LOAD position during the loading.
Both ends have been detected at the LOAD position when the loading is started.
The aim of Tape position between the starting edge and the finishing
The Tape position is divided into 6 stages between the Tape beginning
edge: "A " and the Tape end edge: "5".
The Tape position is divided into 14 stages between the Tape
beginning edge: "E " and the Tape end edge: "1".
