It is located above 4 and occupies the space on the hybrid card. Inside the optical head, parts such as a laser diode as a light emitting source, an objective lens, an actuator for the objective lens, a prism, and a photodetector are arranged at a predetermined interval, so that the space is larger. Has become. In addition to this, since the optical head moves linearly in the lateral direction of the card in order to access the target track on the optical medium portion 24, the space on the hybrid card for this linear movement is also occupied.

読み出しにかかる時間が著しく増大してしまう。In this way, when the external contact mechanism and the pressing / separating mechanism occupying a large space on the hybrid card and the optical head are simultaneously positioned above the hybrid card, that is, the external contact mechanism and the IC contact terminal 22 are connected. When the hybrid card is driven in the track extending direction while keeping the contact and the optical head tries to scan the optical medium section 24, the optical head interferes with the external contact mechanism, and the entire optical medium section 24 is scanned. It becomes impossible. Make sure that the optical head and the external contact mechanism do not interfere.
Although it is conceivable to reduce the number of tracks of the optical medium portion 24, in this case, the recording capacity may be significantly reduced. When writing and / or reading the information of the IC chip, there is a method of driving the card mounting table to a predetermined position and then contacting the IC contact terminal 22. It is impossible to write and / or read information to and from the IC chip at the same time. Information may be written and / or read from the optical medium section 24 after the contact between the IC contact terminal 22 and the external contact mechanism is temporarily cut off.
Since the power supply to the chip is turned off and the writing and / or reading of information of the IC chip has to be performed again from the initial processing, the time required for writing and / or reading significantly increases.
