2. Description of the Related Art Conventionally, music software is generally purchased by a user going to a record store and purchasing a reproduction-only medium such as CD (compact disk) software or MD (mini disk) software. It was a target. For this reason, it is necessary for a record store to keep a large number of music software that the user will purchase as stocks, and depending on the store space, the types and quantity of music software that can be kept are greatly limited.

[0003] In addition, there is a need on the part of the user to easily purchase desired music software in a store that is often present nearby, such as a convenience store or a stand in a station. However, convenience stores and shops at train stations generally have limited space, and many music software cannot be kept in stock.
Meeting such needs of the user has been difficult.

[0004] Under such circumstances, in recent years, a "music distribution system" capable of selling a large amount of music software in a small store space has attracted attention. The music distribution system is, as it were, a vending machine for music software, and the outline thereof is as follows. That is, the music distribution system has a delivery unit for a recording medium and a storage unit for music software,
When the user inputs a purchase price and selects music desired to be purchased, the user selects music software desired to be purchased from the music software stored in the storage unit by distribution, and records the music software on the MD (recording). After the recording is completed
(See Nikkei Zero One, May 2000, page 61).

An MD used as a recording medium in such a music distribution system is a reproduction-only recording medium C
Unlike D, it is a recording medium capable of recording / reproducing. Therefore, in the music distribution system, it is not necessary to always keep various kinds of CD software in which music data is recorded in advance, and a very wide variety of music software is sold in a small store space by using only unrecorded MD and music data. It becomes possible.

However, an MD used as a recording medium in a music distribution system is
There is a disadvantage that the recording speed (recording speed) is low.

That is, it is difficult to increase the recording speed of the magneto-optical recording system employed in the MD capable of recording / reproducing. According to the research by the present inventors, the practical recording speed is as follows. At present, it has been found that about twice the speed is the limit. Therefore, for example, when music software is sold by a music distribution system for a total playing time of 60 minutes, assuming that the data compression ratio is four times, the time required for recording such music data on an unrecorded MD is considered. Is 7.5 minutes.

[0008] As described above, it takes 7.5 minutes to sell music software for 60 minutes, which causes various disadvantages for both the seller and the purchaser. For example, for a seller, there is a disadvantage that profitability is low because the sales volume per unit time is small, and for a user, after purchasing a price and deciding to purchase, the user actually receives the MD which is a product. The disadvantage is that it takes too much time and is inconvenient. In addition, considering the risk that a third party may bring back the MD, which is a product, the user cannot leave the music distribution system until the MD is received, which places a heavy burden on the user.
