It is necessary to develop convenient instruments which can offer useful informations to seismologists without increasing the burden of the station keepers and seismogram interprefers, in order to deploy high quality seismolographic net-work in local as well as in global scale. One of the important developments to meet the above requirements is to construct a longterm recorder to place at remote place where very low ground noise level is expected, but, on the contrary, we have to encounter difficulties to fnd local station keeper to entrust frequent visit to the recorder. For this purpose, long-term recording magnetic tape recorder has been developep by several authors.
