Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain magnetic tape, relay history, formats and preservation from recording technology and archival sources, describe the formats the registry aliases name, and distinguish magnetic tape from magnetic disks, optical media, the cassette as a housing and wire recording.

A recording medium consisting of a thin plastic film coated with magnetisable particles, used for audio, video and data storage in reels, cassettes and cartridges, including the historic Soundmirror recorder, consumer video formats such as Compact Video Cassette, Akai VK and Hi8, toy and niche formats such as Bandai micro cartridges and Pocket Rockers, and enterprise data tape such as LTO that remains in use for archival backup.

What it is for: Recording and storing audio, video and data.

It can be explain technology; relay history and formats; describe named formats; distinguish related media.

Distinguishing features

Sequential access

Magnetic coating

Many formats

Long archival life

What it looks like

Thin brown or black ribbon on reels or in cassettes.

Physical character

Magnetophon: 1935 year - AEG, Germany

Soundmirror: 1947 year - Brush Development Company

LTO-9 native capacity: 18 TB

Hi8 introduced: 1989 year - Sony

How it is recognised

Plastic film with magnetic coating

Soundmirror, Compact Video Cassette, Akai VK, Hi8, Bandai micro cartridge, Pocket Rockers

Disks store on platters; optical media use lasers; a cassette is the housing; wire recording used steel wire

What the second pass must settle

  • Should the consumer video formats be separate primary entries?
  • How should archival sources be linked?
  • The registry entry has merged aliases naming specific products; should they be split off?
