Imation textured backcoating on Black Watch brand cartridges safeguards your data by repelling error-causing static electricity. Imation backcoating also acts like a cushion to safely absorb wound-in debris to decrease the chance of data loss and minimizes inter-layer slippage for uniform signal output. ±30 Oe using VSM with time constant of 0.3 seconds. Broad Band 30 dB minimum
