TAPE MATERIAL AND CAPACITY EVIDENCE RECORD
Purpose: distinguish material results, recording demonstrations and product capacity.
Use: complete one record per source; compare only matching units and boundaries.
Source title / URL / publication date / date read:
Claim in your own words:
Evidence stage (material / coating / recording experiment / cartridge / restore):
Measured / calculated / projected / unknown:
Material composition and particle dimensions (nm; include distribution and shell):
Coercivity (units, temperature, orientation):
Magnetization (units and mass/volume basis; measured sample or inferred core):
Head, spacing, coating and recording conditions:
Density (bits per area; raw channel bits or user data):
Error criterion / tested duration / number of samples:
Capacity (decimal TB or binary TiB; native or compressed):
Usable area and format overhead; avoid subtracting overhead twice:
Exact drive, media and software compatibility evidence:
Restore check (files selected, date, comparison method, result):
Missing evidence / next action / owner:
Conclusion supported by this source:
Example only: 100 in^2 * 80e9 bits/in^2 / 8 = 1e12 bytes = 1 decimal TB.
With hypothetical 15% format overhead: 0.85 TB. These are invented inputs.
