Claims
- 1. A cartridge adaptor for allowing a disk apparatus designed to receive a first cartridge accommodating a first disk and provided with a shutter opening and closing mechanism for opening and closing a shutter of the first cartridge, to perform at least one of data reproduction and data recording form and in a second disk accommodated in a second cartridge, the second cartridge being smaller in external profile than the first cartridge and wherein the second cartridge is provided with shutter means for exposing an opening in the second cartridge for insertion therethrough of at least a head for at least one of reproducing and recording and a disk driving mechanism of the disk apparatus, the cartridge adaptor comprising:
- a housing for accommodating the second cartridge, the housing having an opening for insertion therethrough of at least the head and the disk driving mechanism;
- shutter opening means movable in the housing and having a first engaging section engageable with the shutter opening and closing mechanism of the disk apparatus and a second engaging section engageable with the shutter means of the second cartridge; and
- biasing means for biasing the shutter opening means in the direction of closing the shutter means,
- wherein the housing has an external profile substantially identical with the profile of the first cartridge so as to be received by the disk apparatus, and
- wherein, when the second cartridge is mounted in the cartridge adaptor, the position and height of the second disk relative to the cartridge adaptor substantially correspond to the position and height of the first disk relative to the first cartridge and
- wherein when the cartridge adaptor is inserted into the disk apparatus, the first engaging section engages the shutter opening and closing mechanism of the disk apparatus and causes the shutter opening means to move through a first distance, after which the second engaging section engages the shutter means and moves through a second distance to move the shutter means, the second distance being less than the distance of movement of the shutter of the first cartridge when the first cartridge is inserted into the disk apparatus.
- 2. A cartridge adaptor according to claim 1, wherein:
- the shutter opening means includes a first opener which includes the first engaging section and is movable by the distance of movement of the shutter of the first cartridge; and a second opener which has the second engaging section and a contact section contactable with the first opener and movable by the distance of movement of the shutter means of the second cartridge when the cartridge adaptor with the second cartridge is inserted into the disk apparatus; and
- when the cartridge adaptor is inserted into the disk apparatus, the first opener moves by the difference between the distance of movement of the shutter of the first cartridge and the distance of movement of the shutter means of the second cartridge and then the contact section of the second opener contacts the first opener.
