A tape drive (10) for use with a cartridge (24) having a storage tape (30) that moves along a tape path (32) includes a drive housing (12) defining a drive interior (62), a circuit assembly (42) that generates heat, and a thermal insulator (44). In one embodiment, the thermal insulator (44) is positioned between a portion of the storage tape (30) and the circuit assembly (42). The thermal insulator (44) can be formed from a flexible, plastic material and/or can have a thermal conductivity of less than approximately 50 W/mK to decrease the transfer of heat between the circuit assembly (42) and the storage tape (30). The drive interior (62) can have a first region (64) that includes a portion of the tape path (32), and a second region (66) that includes the circuit assembly (42). The drive housing (62) also includes a plurality of ventilation apertures (74) positioned so that the area of the ventilation apertures (74) extending between the exterior of the drive housing (12) and the first region (64) can be less than approximately 200 percent of the area of the ventilation apertures (74) extending between the exterior of the drive housing (12) and the second region (66). A tape drive assembly (72) includes the tape drive (10) and an air mover (72) positioned outside of the drive housing (12). The air mover (72) moves air through the ventilation apertures (74) of the first region (64) and the second region (66) at a ratio of less than approximately 2:1.
