ABSTRACT:
This invention provides a memory card (1) that is to be used as a storage medium in a host apparatus that can record and reproduce data. The memory card has a first memory (12-1), a second memory (12-2), a first switch (13) for changing over one memory to the other, and a second switch (14) for connecting and disconnecting an insertion/removal detecting terminal INS. The first and second switches work as a slide switch (6) provided on the housing is operated. The first switch has a contact for selecting the first memory, a contact for selecting the second memory, and a contact located between these two contacts, for selecting neither memory. The second switch connects the terminal INS to the ground while the first switch remains connected to the contact for selecting the first memory or the contact for selecting the second memory. The second switch opens the terminal INS while the first switch remains connected to the contact for selecting neither memory.
