The built-in 32 MB flash memory uses a high-capacity IC chip. This technology allows you to record over old messages again and again with distortion-free clarity. The standout feature on the ICD-MX20 is the hybrid storage.
It gives you the option of using the built-in flash memory or utilizing Memory Stick Duo or Pro Duo media cards, providing virtually unlimited capacity. This is a great feature if you're at a long conference, and don't have time to download your files to a computer. Just put in a new Memory Stick media card, and keep recording. Each card can hold over 300 personalized folders, which makes organizing your audio a simple process.
The ICD-MX20 allows you to record at different quality levels. The high-quality, two-channel STLP recording mode allows up to 165 minutes of recording. This is perfect for recording interviews that you may want to reproduce in digital format. If you're just taking personal audio notes, switch the voice recorder to LP mode and take full advantage of over 11 hours of lower quality recording.
