A downhole recorder system for use with a downhole assembly to be lowered into a borehole comprises at least one recorder uniquely associated to a determined sub-assembly of the downhole assembly. The at least one recorder allows to store operating data related to the determined sub-assembly. The stored operating data are extractable at least when the determined sub-assembly is disassembled from the downhole assembly.
