Test Cassettes

A minimal first product page for Spin-Tape calibration cassettes.

The first planned line covers the basic checks needed in cassette deck service: level, speed, wow & flutter, azimuth and high-frequency response.

ST-L400-250

400 Hz / 250 nWb/m

For level checks and alignment workflow.

ST-S3150

3150 Hz or 3000 Hz

For speed measurement and wow & flutter checks.

ST-H10K

10 kHz

For azimuth, playback HF and head alignment checks.

ST-L400-200-CUE

400 Hz / 200 nWb/m + voice + 9 Hz cue 2 sec

For cassette loader workflow and cue detection tests.

Status: planned / prototype / pre-production. Final tolerances and public claims must be confirmed by measured batches.
