朋友的TEAC R-61机该选用哪种磁带？

前天去朋友那里，看见这个闲置的好几年的东东。
朋友说，用普通磁带录音试过，不行。
这种数字式录音机应该用哪种磁带？

金属粉末磁带。年代太久远，忘记具体型号了

刚才搞错了 . . . . . .
用Data卡式帶作资料保存。
Records up to 4 channels simultaneously on a cassette data tape.(It will operate satisfactorily with standard tapes). Will record DC signals using FM modulated channels. Uses phase-lock loop servo controlled capstan, rather than flywheel to regulate tape speed.

感谢G版！
我的英文太差了，看那段E文发懵。
是不是只能用于数据保存？能应用于音频吗？

Teac R61D

This cassette recorder was intended to be used for recording scientific data.四轨跡科学资料纪录 (There also was a version for professional audio recording. 但也是专业录音 ) As far as I know, it was used to collect data from CSIR's “Heavy Vehicle Simulator”, or maybe for braking tests on heavy vehicles.
Teac R61 D Data Recorder - Front and Side Views

It can be used to play stereo tapes可重放卡式声帶, but since it is a four-channel recorder但因属四轨跡, it can't record stereo without erasing the recording on the other side of the tape故声帶须先消磁后才能用. Since the purpose of the recorder is to record data由于主要用作资料纪录, music played back might sound a little odd to the trained ear, as there are no equalisation circuits重放时高频便會搶耳，原因是沒有均衡電路. (It sounds perfectly good to me). Two of the channels may be used to record DC data. This is done by recording a frequency-modulated tone onto the tape录音/资料 用FM方式调制.

The tape transport has motors for fast-forward and rewind, as well as a DC servomotor to operate the tape capstan. There is no flywheel to regulate the tape speed – this is all done electronically using a phase-lock loop用了相鎖环作速度监察 . . . 不用离心式调速.

If you open most domestic tape recorders, the cabinet is mostly empty space. By way of contrast, this small device is jam-packed full of electronics and weighs “a mere 5kg without batteries” according to the manual. Since it requires 6 “D Size” batteries, you can imagine its really very heavy for its size-about the same weight as a house brick.

It had been discarded because it no longer worked and, in any case, computers with analogue to digital converter cards had taken over the job of doing the recordings. Not that there was a great deal wrong – a small magnet had become unstuck from one of the spools. The magnet was used to activate a reed switch informing the recorder that all was well with the tape spooling. (I am not claiming to be a wizard with tape mechanisms, nor did I get lucky, it took me ages to puzzle out why it wouldn't work and what a reed switch was doing seemingly in the middle of nowhere.) The tape transport bears no resemblance whatever to that of a domestic tape recorder.

这机只能用其独特的方法（FM）录音，一般的卡式声带用不了 . . .
