Abstract

PURPOSE:To execute sound recording on a tape without waste by driving a tape at a tape speed calculated based on a reproducing time and the length of the tape and also recording the speed on the tape in the case of sound recording, and driving the tape at the speed which is recorded on the tape in the case of reproducing. CONSTITUTION:This tape recorder is provided with a means 1 for inputting reproducing time information, a means 5 for inputting the length of the tape, a means 4 for calculating the tape speed based on the reproducing time and the length of the tape, and a means 2 for recording the calculated tape speed on the tape. It is also provided with the means 2 for reading out the recorded tape speed, and a tape driving means 3 for driving the tape at the detected tape speed in the case of sound recording and driving the tape at the read-out tape speed in the case of reproducing. Then, the tape speed is changed in accordance with the reproducing time for music to be sound-recorded, etc., and the length of the tape. Thus, sound recording is efficiently executed on the tape.

Description

[Detailed Description of the Invention] [Summary] A tape recorder that records music onto a tape without waste by changing the tape speed according to the playback time and tape length of the music, etc. to be recorded.

[Industrial application field]

The present invention relates to a tape recorder, and particularly to a tape recorder that can efficiently record music and the like onto tape.

[Conventional technology]

Tape recorders are mainly used to record radio broadcasts, records, compact discs (CDs), etc. onto tape. In recent years, these audio devices have become multi-functional. For example, when recording from a CD to tape, the information on the track number and song time recorded on the CD can be used to record the audio (split) on sides A and B of the tape. side A and B of the tape so that it is recorded
There are tape recorders and the like that automatically select and record songs on a tape.

[Problem to be solved by the invention]

However, due to the recordable time of the prepared tape, the CD
If the total performance time is different from the total playing time, it may not be possible to record the entire song, or the unrecorded portions may become long, making it difficult to use the recorded tape.

[Means to solve the problem]

The present invention solves these problems and includes a playback time input means for inputting playback time information from a playback machine;
tape length input means for inputting a tape length; tape speed calculation means for calculating a tape speed from the playback time input by the playback time input means; and the tape length input by the tape length input means; and the tape speed calculation means tape speed recording means for recording the tape speed calculated by the tape speed on the tape; tape speed reading means for reading the tape speed recorded on the tape; and during recording, the tape is driven at the tape speed detected by the tape speed calculation means. ,
The present invention is characterized by comprising a tape drive means for driving the tape at a tape speed read by the tape speed reading means during reproduction.

[Effect]

When recording on a tape, the tape is driven at the tape speed calculated from the playback time and tape length, and the tape speed is also recorded on the tape, and when playing back, the tape speed recorded on the tape is The tape is driven by

〔Example〕

Hereinafter, the present invention will be explained in detail using the drawings.

In this embodiment, a tape recorder that records CD songs on tape will be used as an example, but the playback device may also be a radio, analog record player, tape player, etc., and the recording device may be a digital audio player. It is also possible to use a tape recorder or the like.

FIG. 1 is a configuration diagram showing one embodiment of the present invention, in which 1 is a CD player, 2 and 3 are recording/playback heads, amplifiers, etc. of a tape recorder, respectively, and record/playback for recording/playback. The tape drive unit consists of a drive unit, a motor, gears, etc., and drives the tape. 4 is CD player 1
It consists of a microcomputer, etc., which controls the tape drive means so that the tape is driven at a tape speed according to the CD playback time from the input section, the tape length from the input section consisting of operation switches, and the tape speed from the recording/playback section 2. This is the control section.

Next, the operation of the control section 4 will be explained. FIG. 2 is a flowchart showing the operation of the control section 4, in which (A) shows the operation during recording, and (B) shows the operation during playback. First, the operation during recording will be explained. When the recording operation is performed, first step R is performed.
At step 1, the tape length is input from the input section 5. In this embodiment, the tape length is manually input by the operator from the operation unit 5, but the tape length can be calculated by driving the tape slightly and determining the tape length from the rotational speed of both reel shafts at that time, the difference therebetween, the rate of change, etc. can also be estimated. In step R2, the playing time T of the CD is input. This can be obtained from the lead-in information of the CD. In step R3, the tape length and playing time T
Calculate the tape speed from Specifically, the standard speed for cassette tapes is 4.36 cm/see, so the tape speed is 4.36 x L/T cm/
sec.

In step R4, the tape speed is recorded on the tape, and in step R5, the tape drive unit 3 is controlled to achieve the tape speed. Note that the tape speed can be controlled by a method such as controlling the voltage applied to the motor. Then, the process moves to step R6 and starts recording the CD.

Next, the operation during playback will be explained. In step PI, the tape speed recorded on the tape is read. Then, the value read in step P2 is set as the tape speed. Note that if the tape speed is not recorded, the tape speed is set to the standard speed (4.36 cm/5ec). Step P3
Then, the tape drive section 3 is controlled so that the set tape speed is achieved. Then, the process moves to step P4 and a reproducing operation is performed.

In addition, the tape speed is recorded on the tape for song 1 on the tape! I
T (fl? between songs and sides), and when playing back, search between these songs (for example, by searching for unrecorded parts or by recording a specific frequency between songs and searching for this frequency) to determine the tape speed. There is a method of detecting the tape speed, a method of recording the tape speed using a signal with a frequency outside the audible band (high or low frequency) over the entire tape, or a method of pasting a magnetic sheet on the cassette tape pack and detecting its magnetic properties. Recording/recording using body sorting
There is a way to play it.

〔Effect of the invention〕

As explained in detail above, according to the present invention, when recording on a tape, the tape is driven at a tape speed calculated from the playback time and the tape length, and the tape speed is also recorded on the tape. Furthermore, when playing back the tape, the tape is driven at the tape speed recorded on the tape, so recording can be done without wasting anything on the tape.
