The miniature motorized microdrive which is applicable to the neural signal recording in gene-modifiable mice is presented. The microdrive is manipulated with direct driving method of micro motor within the range of 2.8㎜, with the resolution of 0.742 ㎜. A moving electrode in a mouse brain is monitored with an integrated MR(Magneto-Resistive) sensor. This microdrive, which is trapezoidal, has the length of 7.1㎜, the width of 5㎜, the height of 22.5 ㎜ and the weight of 1.45g only. The displacement of the microdrive was evaluated and verified in the range of 1000 ㎛. The neural signal of the mouse in anesthesia was recorded successively with the microdrive moving.
