Secure Digital/MMC cards
Secure Digital (SD) cards and the identically sized but less flexible MultiMediaCard (MMC) are still other memory card formats similar to CompactFlash. Secure Digital cards are a newer format that has swept the industry in a relatively short period of time because the smaller size (roughly % x 1>4 inches) of the SD card allows designing smaller cameras. One key difference between MMC and SD cards is that the Secure Digital version allows encryption of the files to prevent tampering. SD cards also offer higher performance and thus are preferred over MMC cards for digital cameras.
Using a Secure Digital card for image storage is essentially the same as using a CompactFlash card except that the card itself is slightly smaller, which means that the sockets in the camera and the card reader must be made to fit the Secure Digital card. The Secure Digital format is not interchangeable with the other formats.

Memory Stick
The Sony Memory Stick is one more form of memory card, functionally similar to the CompactFlash and Secure Digital cards. Sony uses the Memory Stick in several of its high-end digital cameras and also in digital video cameras, music players, and so on, which means that you can move your Memory Sticks between devices and use them for storing pictures, music, and other files.
The Memory Stick is about the size of a stick of chewing gum and comes in capacities of 32 to 128MB. The newer Memory Stick Pro offers higher capacity but is not backward-compatible with earlier devices that used the original Memory Stick. There is also the half-sized Memory Stick Pro Duo. The latest versions can be purchased in sizes up to 4GB.
Several models of Sony laptop computers include a built-in Memory Stick slot so that you can use the laptop computer to access the contents of your Memory Sticks. You can also use a card reader similar to the card readers for CompactFlash and SmartMedia cards to access Memory Sticks from your desktop computer. The card reader is usually supplied with your camera and attaches to your computer via USB cable.
Here are some pointers for removing, inserting, and accessing files on a Memory Stick:
? To remove a Memory Stick from your digital camera (or card reader), press the eject button next to the slot to pop the stick loose, grasp the exposed end of the stick, and slide it out of its slot.
? To insert a Memory Stick into the camera (or card reader), insert the stick into the slot in the direction of the arrow marked on the surface of the stick. The arrow and a clipped corner help you orient the stick properly. The stick goes into its slot in only one way. Push the stick in firmly but gently to seat it properly.
? Like the other memory cards, after you insert a Memory Stick into the card reader attached to your computer, you can access and manipulate the files on the stick as if they were located on a virtual disk drive. Copy, move, and erase the files using your normal file management tools.
The Memory Stick includes an Erasure Prevention Switch that lets you protect the contents from accidental erasure. Make sure the switch is in the Off position when you want to record images onto the stick in your camera or erase files in the card reader.
Book II
CompactFlash cards, Secure Digital cards, Memory Sticks, and the like are often called digital film because inserting a memory card into a digital camera is analogous to loading a conventional camera with a fresh roll of film.

SmartMedia cards
SmartMedia cards have faded almost completely from the scene and exist today only as memory options for older digital cameras. They are similar to CompactFlash cards but in an even smaller package, and they are limited to only 128MB capacity.
PC Cards
The oldest format for a memory card still in use is the PC Card, also known as ATA Type II PC Cards or PCMCIA cards. PC Cards come in many different forms and are not limited to memory configurations. They are typically used to provide plug-in components, such as modems or network interface cards, for laptop computers equipped with a PC Card slot. Memory cards and miniature hard drives have in the past also been furnished in the PC Card form. Today, PC card slots are used primarily for plugging in devices like wireless network cards. My own Toshiba laptop has a memory card slot for SD cards, but accepts Compact Flash cards only through an adapter plugged into its PC Card socket.
Mini-CD
To combat the problem of the limited capacity of floppy disk drives (used in some very early Sony digital cameras), Sony built some digital cameras with a mini-CD drive in place of the floppy disk drive. The camera actually includes a CD burner to record picture data onto mini-CDs, which are smaller-diameter versions of standard CDs. A standard CD-ROM drive can read the mini-CDs, and because CD drives are standard equipment on almost all computers, the mini-CD enjoys the same universal accessibility as floppy disks. The downside is that the mini-CDs arenít readily available for purchase like floppy disks or even memory cards are.
