From the necessity of study about the effect of dynamic charachteristics of recording drum in Maihak indicator and its available limits, some experiments were tried to make clear the action of this system, and then calculated results in theoretical analysis were compared with experimental data. From the discussion about the factors that have effect on the available limits of drum, including transmission system, I came to the following conclusions. a) Since diagram accuracy is generally influenced by transmission system within the compass of calculated value, it is most important not to add unnecessary action in transmission cord and guide pulley. b) The smaller moment of inertia I is, the better it is, but in order to save strain as much as possible for variable tension, it is necessary to select suitably spring constant k according to initial tension, material and dimmension of cord. Considering to these points, available value can be made to attain at least to the same compass 350 rpm as pressure system of M3 type, while this value reduces easily by want of care.
