2.1.5 Maintenance and inspection
1. Location of major mechanical parts
In this chapter, the two mechanism speeds are described by comparing the speeds of the standard type and the high-speed
FF/REW type.
It is possible to distinguish between these two types of mechanism by the diameters of their capstan pulleys.
The capstan pulley diameter for the standard type is approx. 32 mm.
The capstan pulley diameter for the high-speed FF/REW type is approx. 43 mm.
For information on the different parts used in the two mechanism types, please refer to the "Replacement of major parts".
