Introduction

...

Digital8 was introduced by Sony in 1999. It is a is a consumer digital video recording format that blends the DV video recording specification with previously existing analog Video8/Hi8 videocassette equipment. Digital8 is the only videocassette format that employs the DV specification on 8 mm videotape.

Digital8 video can be recorded to Video8, Hi8 or specialty Digital8 cassettes, however the use of Video8 cassettes for this purpose is discouraged. The drum in a Digital8 camcorder rotates twice as fast as Hi8 equipment, which reduces the recording time of these cassettes by half. For example, a 120 minute Hi8 cassette will record 60 minutes of Digital8 video. The videotape used in Hi8 and Digital8 cassettes is thin and prone to stretching. Longer tapes are more vulnerable to this type of damage.

Compared to MiniDV, the Digital8 format was less popular in the consumer digital video market and the production of Digital8 recording equipment was discontinued in 2007.

Identification

...

Flaking/missing magnetic oxide particles are an indication of tape deterioration. This type of drop-out cannot be corrected physically. 

Mould

Image RemovedImage Added

Description

Active mould is generally moist while dormant mould is dry and dusty. Mould growths may be white, black, brown or mustard-coloured and usually have a pattered, fuzzy, or thread-like appearance. Mould can cause permanent damage to tapes over time if not removed. Fungus and mould is also a significant health hazard and affected materials should be handled using gloves and masks. 

...

Mouldy tapes should be isolated from unaffected materials to prevent cross contamination. Store tapes at a temperature of 24°C in an environment with effective air circulation and less than 50% Relative Humidity. Loose mold can be vacuumed from the tape pack and then the tape should be treated with an appropriate fungicide.  

Stretching and breaking

Cause

Stretching, wrinkling and breaking of video tape usually results from improper handling or use of playback equipment.  

...

Stretching can distort the tape signal however data can usually be recovered (with a decrease in signal quality). 

Accidental recording
