IC MEMORY CARDS

Cards to be used (recording media)

2 The DN-F20R uses IC memory cards as the recording medium. Denon IC memory cards are sold separately.

2 In addition to Denon IC memory cards, we also recommend the following SanDisk Compact Flash™ (*

) cards:

Note

• The DN-F20R accesses (reads and writes) large amounts of

audio data on the IC memory card in real time.

In order to process this data, the IC memory card itself must

offer sufficiently high access speed.

If cards other than Denon IC memory cards or the

recommended Compact Flash cards are used, it may happen

that the IC memory card’s access speed is too slow, in which

case recordings may randomly stop or normal recording may

not be possible. Also, the set may not be able to properly

identify cards other than the recommended Compact Flash

cards.

The above table is valid as of February, 2000. Some cards

may no longer be produced or sold.

Recording time

The recordable time on the DN-F20R depends on the card capacity and recording bit rate.

A formula for roughly calculating the recording time and examples are provided below.

2 Calculating the recording time (approximate)

Card capacity (MB) x 1024 (kByte) x 8 (bit) = Card capacity (kbit)

Card capacity (kbit) ÷ Recording bit rate (kbps) ÷ Number of channels = Recording time (sec)

Recording time (sec) ÷ 60 = Recording time (min)

Example: With a 32 MB card

ISO/IEC 11172-3 MPEG1 Layer2 16bit Fs = 48kHz

ISO/IEC 13813-3 MPEG2 Layer2 16bit Fs = 24kHz

The recording time may decrease if small files of about 10 kB or less in size are created.

Formatting

2 Format type

The DN-F20R is only compatible with the 16-bit FAT format. Attempting to use cards formatted in the 12-bit FAT format will result in card

errors. If this happens, format the card on the DN-F20R (note that when this is done any data on the card is deleted). The set automatically

formats cards in the 16-bit FAT format. Also note that when 12-bit FAT cards are formatted in 16-bit FAT format on the DN-F20R, some PC

applications may no longer be able to recognize them.

2 Cluster size

The cluster size is the smallest unit of data when writing on IC memory cards.

The cluster size may change when cards are formatted on PCs or any devices other than the DN-F20R.

To ensure proper recording, the set carefully checks not only the card’s own access speed but also the cluster size. Changing the cluster size

may result in card errors, even when using a recommended card. If this happens, format the card on the DN-F20R.

2 Double recording (1 & 2 REC card mode)

Even higher speed is required for double recording, so be sure to use recommended IC memory cards of the same maker, the same model

(capacity) and the same cluster size for double recording.

As long as the cards’ manufacturer and cluster size are the same, recording may be possible even if the models (capacities) are different.

If recording is not possible, either the recording will stop or an error message will be displayed when recording starts.
