What early video recording device did Baird develop between 1926 and 1928?

Answer

Phonovision

Phonovision was an early video recording device developed in the late 1920s that acted as a precursor to modern on-demand viewing. The system functioned by linking a Nipkow disk, which was used for scanning images, to a record-cutting lathe. This allowed the visual signals of the television system to be captured and stored physically on a record, marking an early attempt at preserving television broadcasts for later playback.
