Holographic recording medium cartridge

Abstract

A cartridge for storing a holographic recording medium designed to allow a user to check whether a holographic recording medium is contained within the cartridge. The cartridge includes a disc tray on which a recording medium may be mounted and a housing that is capable of accommodating the disc tray and wherein a side surface of the housing may be opened. The housing is constructed to prevent the passage into its interior of light to which the recording medium is sensitive (dead band color). The housing, however, includes at least a portion that allows the passage into its interior of light to which the recording medium is not sensitive (e.g., orange through red colors), to allow the cartridge to be visually checked to determine whether a recording medium is contained within it. To further prevent the passage of any damaging light into the cartridge's interior, an elastic (e.g., sponge-like) light shielding material called MOLTOPREN is wound over a circumference of the plate part at a portion of a plate part of the disc tray which is is bonded to a holding part.
