Data recording apparatus for recording a data signal onto a magnetic recording medium and data recording system using the data recording apparatus
A data recording apparatus and a data recording system of the present invention includes buffer memories 2 a to 2 c that accumulate data in a plurality of channels transferred from an external appliance on a channel basis, a data selector 3 that reads the data accumulated in the buffer memories 2 a to 2 c , and a data drive 4 that records the data read by the data selector 3 onto a magnetic tape, wherein the data selector 3 selectively reads the data accumulated in the buffer memories 2 a to 2 c , and outputs the data in an order of recording onto a magnetic tape in the tape drive 4 . According to such a configuration, a data recording apparatus that can be realized at low cost and a recording system using the data recording apparatus can be provided.
1. A data recording apparatus, comprising:
an accumulating portion that accumulates moving image data, in which address data is added to main data in a plurality of channels, transferred from 17 or more external appliances on a channel basis;
a selecting portion that reads the moving image data accumulated in the accumulating portion; and
a recording portion that records the moving image data read by the selecting portion onto a magnetic tape,
wherein a plurality of the accumulating portions are provided independently for each of the external appliances,
the selecting portion selectively reads the moving image data accumulated in the plurality of the accumulating portions, and outputs the moving image data in order of recording onto the magnetic tape in the recording portion, and
the recording portion records the moving image data onto the magnetic tape at a data transfer speed of 20 mega bits per second or more using a head with 8 channels or more so that a plurality of data tracks are formed simultaneously.
2. The data recording apparatus according to claim 1 , wherein the recording portion records the moving image data in real time onto the magnetic tape.
3. A data recording system, comprising:
17 or more external appliances capable of outputting main data; and
a data recording apparatus capable of obtaining the main data output from the external appliances,
wherein the data recording apparatus includes:
an accumulating portion that accumulates moving image data, in which address data is added to the main data in a plurality of channels, transferred from the external appliances on a channel basis;
a selecting portion that reads the moving image data accumulated in the accumulating portion; and
a recording portion that records the moving image data read by the selecting portion onto a magnetic tape,
wherein a plurality of the accumulating portions are provided independently for each of the external appliances,
the selecting portion selectively reads the moving image data accumulated in the plurality of the accumulating portions, and outputs the moving image data in order of recording onto the magnetic tape in the recording portion, and
the recording portion records the moving image data onto the magnetic tape at a data transfer speed of 20 mega bits per second or more using a head with 8 channels or more so that a plurality of data tracks are formed simultaneously.
4. The data recording system according to claim 3 , wherein the recording portion records the moving image data in real time onto the magnetic tape.
