The corresponding changes, approved by ALICE collaboration, have been made in the AliRoot framework. With due regard for new algorithm the data have been processed, and one-particle transverse momentum and hadron velocity distributions have been extracted. Comparative procedure analysis of the several algorithms for particle coordinate reconstruction in the stripped detector of internal tracking system of ALICE detector has been made. Some improvements in the program codes to enhance the tracking accuracy and efficiency have been proposed. It is especially important in the events with high multiplicity when studying physical phenomena associated with matter caused by pp- and PbPb-collisions at LHC.
