Narrative:
While working the monitor 'O' (center final-runway 9R at atl) while we were conducting ILS/prm approaches; I was monitoring arrivals to atl on one of the prm scopes. A B757 was on approximately 14 mile final to runway 9R and descending through 4800 when the 'data tag' for the B757 dropped off the prm scope for 30 to 40 seconds. Since there is no primary radar tag associated with the 'ARTS tag' on the prm scopes; it appeared the aircraft had disappeared. The data tag reacquired some 3 to 5 miles down the localizer. Since the aircraft was a B757 per the A80 SOP we are required to have a 'range line' from the B757 to the aircraft trailing; even the range line dropped from the prm scope. This is a common; reoccurring issue with the prm scopes here at A80; and a totally unsatisfactory condition.
