Recording medium driving apparatus

A recording medium driving apparatus comprising:

• a holder into which a cartridge having a recording medium is inserted;
• a head part;
• a cartridge contact preventing mechanism preventing an end of the cartridge from contacting the head part when the cartridge is inserted into the recording medium driving apparatus;
• and
• a deformation preventing mechanism having a first part for preventing deformation of the holder and a second part contacting the cartridge when the cartridge moves towards a disk loading position in the holder;
• the first part of the deformation preventing mechanism being moved from a first position preventing deformation of the holder to a second position wherein deformation of the holder is not prevented by contact of the cartridge with the second part wherein:
• the deformation preventing mechanism comprises a third part which contacts the cartridge part and prevents the head and the cartridge from contacting each other;
• and
• when the first part is moved from said first position to said second position, the third part is moved from the first position to the second position;
• and
• wherein the first, second and third parts of the deformation preventing mechanism are those of an integrally formed member.
