1. A system, comprising:
a memory that stores computer executable components; and
a processor that executes the computer executable components stored in the memory, wherein the computer executable components comprise:
a tape control component configured to:
control a write operation, wherein the write operation comprises writing a first data file to a tape, wherein the tape is configured with a series of regularly spaced interrupt points positioned along a length of the tape, and a distance between a pair of adjacent interrupt points equates to a known volume of data stored on the tape for a given feed rate of the tape;
receive a read file instruction identifying a second data file to be read from the tape; and
in response to the read file instruction being received during the write operation, pause the write operation to enable the second data file to be read, wherein the write operation is paused after a first portion of the first data file has been written to the tape, and a second portion of the first data file remains to be written to the tape.
