MO（T2）＝M1（T2）とおいて、 mO・t/T1＝ｎ・（ｔ−T1） となる。The accumulated storage capacity of the storage sending means 3 at time t is M
Assuming that O (t) and M O (T 1 ) = m O , at T 1 <t <T 2 , M O (t) = m O + (t−T 1 ) · = m O · t / T 1 (1) Since the signal transmission speed per unit time is n, the transmission capacity M 1 (t) of the main signal S at time t is: M 1 (t) = n · (t−T 1 ) ............ (2) Thus, time T 2, the signal which has been stored by the storage feeder 3 is sent all, from (1) and (2)
Assuming that M O (T 2 ) = M 1 (T 2 ), m O · t / T 1 = n · (t−T 1 ) Becomes
従って、T2の値は概知のパラメータを入力すれば
（３）式より制御手段７で簡単に求められる。Therefore, the value of T 2 are are easily determined by the control unit 7 from the parameter by entering the equation (3) Gaichi.
従って、制御手段７は記憶送出手段３に対して時刻T1

第１の記録モードで記録するように制御する。Therefore, the control means 7 sends the time T 1 to the storage sending means 3.
<Controls to the transmission of the main signal S is 1 / n of t <T 2 up real time. Further, the recording means 4 is controlled so that the main signal S is recorded in the second recording mode in which the main signal S is recorded at 1 / n of the real time when T 1 <t <T 2 , and when T 2 ≦ t, the tuner 8 is controlled to be recorded in the first recording mode in which the main signal S is recorded on the magnetic tape 1 in real time.

In a short time, send the already stored main signal,
The recording means 4 records the transmitted main signal on the magnetic tape 1 in the second recording mode, and after all the main signals stored by the storage and transmission means 3 have been transmitted, the recording means 4 records the first main signal. The control means 7 for controlling the recording means 4 so as to record the main signal on the magnetic tape 1 in the mode, so that the user can operate regardless of whether the magnetic tape 1 is mounted on the main body of the recording apparatus. All the main signals can be recorded from the time when the recording of the main signals is desired. Further, the recording can be performed continuously without interruption of the recording of the main signal due to the insertion and removal of the tape cassette 2 by the user.
