Compact optical disk device capable of driving various types of optical disks

An optical disk device, for recording and reproducing an optical disk and which is capable of being applied to a plurality of optical disks differently normalized from each other, comprising:

• rotation driving means for supporting said optical disk and for driving rotation of said optical disk;
• a plurality of optical heads which are applicable to said plurality of differently normalized optical disks, respectively;
• single guiding means for guiding each of said plurality of optical heads in a radial direction of said optical disk supported by said rotation driving means;
• pushing means for pushing said each of said plurality of optical heads along said single guiding means;
• container means for containing all of said plurality of optical heads;
• and
• optical head moving means for moving one of said plurality of optical heads from said container means toward said single guiding means or from said single guiding means toward said container means,
• wherein said container means comprises a plurality of containers for said plurality of optical heads, respectively, said optical head moving means comprising a connecting portion for selectively connecting said container means with said single guiding means, a pushing portion for pushing said one of said plurality of optical heads between each of said containers and said single guiding means, and a predetermined rotation axis,
• wherein each of said containers is located at a distance equal to each other from said rotation axis, said connecting portion rotating said container means around said rotation axis so as to connect said container means with said single guiding means.
