The recording data is stored prior to the recording to the HDD, and the reproduced data is stored and output at the time of reproduction. 7 is an A / D for converting external input analog data into digital data
A converter 8 is a D / A converter that converts digital data into analog data and outputs the data. A servo 9 controls movement of the head 2 in accordance with a recording position at the time of reading or writing. Display device for displaying information of
Are operation keys for performing operations such as recording and reproduction.

The system controller 12 includes an operation key 1
In response to the input 1, the RF amplifier 3, the modulation / demodulation device 4, the memory controller 6, the servo 9, the display device 10, and the like are controlled according to the state of the system. The recording / reproducing apparatus is constituted by the above components. Referring to a time schedule diagram showing the relationship between the memory capacity and time in FIG. 3, the horizontal axis t is the time axis, and the vertical axis b is the amount of data stored in the memory 5. The point A in the figure is the recording medium 1
Indicates that the REC key has been pressed before being set in the apparatus, point B indicates that the setting of the recording medium 1 has been completed, and t1 indicates that the setting of the recording medium 1 has been completed after the REC key has been pressed. Indicates the time until. Point C indicates the time when the reading of the TOC information is completed, and t2 indicates the time from when the setting of the recording medium 1 is completed to when the reading of the TOC information is completed.

With respect to the recording / reproducing apparatus configured as described above, the flowchart relating to the recording process of the system controller 12 in the first embodiment of FIG.
The operation at the time of recording the audio data will be described with reference to FIG.
In S1, the input of the operation key 11 is monitored, and the operation key 1 is monitored.
When the operation of the REC key is input to the system controller 12 at time t0, externally input audio data is converted into digital data using the A / D converter 7, and the converted digital data is converted to digital data. The storage in the memory 5 is started at the point A in FIG. At the same time, it waits for setting (mounting) of the recording medium 1. In S2, it is confirmed whether or not the recording medium 1 is set in the apparatus. If not, the process returns to S1.
The point B in FIG. 3 is when the setting of the recording medium 1 is completed at time t1 after the REC key operation in S2, and the TOC information recorded in the recording medium 1 is taken in by the head 2 and amplified by the RF amplifier 3 in S3. Then, the data is demodulated into digital data by the modem 4, and the TOC information is managed by the system controller 12. During this time, voice data is accumulated in the memory 5.

Assuming that the reading of the TOC information has been completed at point C in FIG. 3 after t2 hours from the completion of the setting of the recording medium 1,
At this time, the maximum data amount is stored in the memory 5,
From FIG. 3, the capacity of the memory 5 requires at least F bytes. This capacity F bytes is obtained by (t1 + t2) × (the amount of data accumulated per second). In S4, if the REC key is input in S1 and there is audio data stored in the memory 5, this is read out via the memory controller 6 in accordance with a command from the system controller 12, and the read audio data is used by the modem 4. The data is modulated, amplified by the RF amplifier, and written on the recording medium 1 by the head 2. During this time, if the write processing speed to the recording medium 1 is higher than the speed of the input data, the amount of data stored in the memory 5 gradually becomes small as shown by the path G in FIG. If the writing is temporarily stopped, the amount of data stored in the memory 5 increases. Thus, the amount of data stored in the memory 5 changes as indicated by the path G. On the other hand, in the conventional configuration in which the REC key is received after the reading of the TOC information is completed, the route starts from the point C and follows the route I.

As described above, according to this embodiment, recording can be started even when the recording medium 1 has not been set yet and the reading of the TOC information has not been completed. (Embodiment 2) Next, a case will be described in which after the recording medium 1 is set, it is confirmed that the REC key has been operated and recording in the memory is started. In this embodiment, the block diagram of the recording / reproducing device of FIG. 1 and the time schedule diagram showing the relationship between the memory capacity and time of FIG. 3 are used together with the flowchart of the recording / reproducing device of this embodiment of FIG. I will explain. In this embodiment, the hardware configuration is the same as that of the first embodiment, and only the software of the system controller 12 is different.

The operation of the recording / reproducing apparatus configured as described above will be described below. In S8, it is confirmed whether or not the recording medium 1 has been set in the apparatus. If the recording medium 1 has been set, the input from the operation keys 11 is confirmed in S9. When the operation of the REC key among the operation keys 11 is input to the system controller 12, external audio data is converted into digital data using the A / D converter 7,
The converted digital data is stored in the memory 5 using the memory controller 6. If the REC key input in S9 is performed after the setting of the recording medium 1 in S8, the state becomes the point B in FIG. 3 and the accumulation of data in the memory 5 is started. S10
Then, TOC information is taken from the recording medium 1 by the head 2 and R
The signal is amplified by the F amplifier 3 and demodulated to data by the modem 4.
The system controller 12 manages the TOC information. T
When the reading of the OC information is completed, the state at the point C in FIG. 3 is established. At this time, the amount of data stored in the memory 5 becomes maximum, and the capacity of the memory 5 requires at least E bytes. The E byte is obtained by t2 × (the amount of data accumulated per second). t2 is a time from completion of setting of the recording medium 1 to completion of reading of the TOC information. In S11, the audio data stored in the memory 5 is read through the memory controller 6 in accordance with a command from the system controller 12, the read audio data is modulated using the modem 4, and is written on the recording medium 1 by the head 2. Memory 5
The upper data amount changes like the path H in FIG.
