Described herein are embodiments for utilizing stored write environment conditions for read error recovery. A tape drive measures read environment conditions as a result of receiving a read command to read data from a portion of tape and compares the read environment conditions to the write environment conditions stored for that portion of tape. If the read environment conditions are not within the predetermined range of the write environment conditions, then the handling of the tape is altered to improve read element placement on the tape by accounting for expansion and contraction of the tape based on the stored write environment conditions. The handling of the tape is altered by at least one of increasing or decreasing the tension of the tape, offsetting the tape head up or down laterally with respect to the tape, and slowing down the movement of tape across the tape head.
