Corrigendum 1 - Information processing - Data interchange on 90 mm (3.5 in) flexible disk cartridges using modified frequency modulation recording at 7 958 ftprad on 80 tracks on each side - Part 2: Track format

This document serves as an official correction for a technical specification concerning data exchange on 90 mm soft disk cartridges using modified frequency modulation. The original standard established recording parameters at a rate of 7,958 revolutions per minute with 80 tracks on each side of the medium. This particular erratum addresses necessary adjustments or clarifications regarding the second part of that specification, which details the track format for the described recording method. Issued by the international body responsible for developing voluntary consensus standards, this correction was circulated to ensure the accurate implementation and interoperability of data storage systems designed according to the primary document. It provides essential amendments to the original text without altering the fundamental technical requirements. Users relying on this standard for developing compatible disk storage hardware or software must incorporate these updates to maintain compliance with the agreed-upon track layout and signal processing parameters defined in the corrected version of the specification.
